Solo Mining Multiple Coins Simultaneously: Diversifying Lottery Tickets

Solo mining a single coin is already a lottery ticket. But what if you could buy lottery tickets for multiple drawings at once — without spending more money?

That’s the core idea behind solo mining multiple coins simultaneously. Instead of pointing all your hashrate at one blockchain, you split your hardware across different algorithms and different coins. Each coin represents an independent lottery.

I tested this approach for two months with hardware I already owned. The data shows: multi-coin solo mining makes mathematical sense if you structure it correctly.

The Logic Behind Solo Mining Multiple Coins Simultaneously

Solo mining is a probability game. Your chances of finding a block depend on your hashrate divided by network hashrate. When you solo mine Bitcoin with an Antminer S21, your probability is roughly 0.000001% per day. Basically zero.

But here’s what changes when you run multiple coins: you’re not improving your odds on any single chain. You’re creating multiple independent probability streams.

Quick math: If Bitcoin gives you a 1 in 100,000 chance per day, and Kaspa gives you 1 in 500 chance per day, you haven’t doubled your overall odds. You’ve created two separate lottery systems running in parallel.

The advantage? Different blockchains have wildly different difficulty profiles. Bitcoin network hashrate is 800+ EH/s. Kaspa network hashrate is around 1.5 PH/s. Ergo sits at roughly 15 TH/s. These aren’t comparable — they’re different games entirely.

When you solo mine multiple coins simultaneously, you’re hedging across difficulty curves, block reward structures, and coin price volatility. Some months Bitcoin is strong. Other months an altcoin pumps 3x and your dormant GPU suddenly found a $2,000 block.

This strategy works best if you already own diversified hardware. One ASIC, two GPUs, maybe a Bitaxe. Each device naturally slots into a different algorithm.

Hardware Allocation Strategy for Multi-Coin Solo Mining

The biggest mistake I see: trying to split a single device across multiple coins. Don’t do that.

Mining software doesn’t efficiently handle simultaneous algorithm switching on the same hardware. You’ll lose 10-15% efficiency in constant handoffs. Instead, assign each physical device to one coin — but run multiple devices in parallel.

Here’s how I structured my own multi-coin solo setup:

• Antminer S19 XP: Dedicated to Bitcoin solo mining via solo.ckpool.org. SHA-256 algorithm, 140 TH/s, 3,010W power draw.
• RTX 3070: Kaspa solo mining through SoloPool.org. kHeavyHash algorithm, 780 MH/s, 120W power draw.
• RX 6800: Ergo solo mining via HeroMiners SOLO. Autolykos2 algorithm, 165 MH/s, 140W power draw.
• Bitaxe Ultra: Bitcoin solo mining as a second independent lottery ticket. Same blockchain, different device — doubles my attempts without changing the math per device.

Each device runs 24/7 on its assigned coin. No algorithm switching. No failover logic. Just four independent lottery tickets running continuously.

Total power consumption: roughly 3,390W. My electricity cost is $0.09/kWh, so about $7.30 per day in operating cost. That’s the price I pay for four simultaneous lottery tickets.

The key insight: you’re not trying to maximize hashrate on any single chain. You’re trying to maximize the number of independent block-finding opportunities across your entire hardware portfolio.

Algorithm Diversity Matters More Than Coin Count

Don’t solo mine five different Ethash coins. That’s not diversification — that’s running the same lottery five times.

Real diversification means different algorithms:

• SHA-256: Bitcoin, Bitcoin Cash (requires ASIC hardware)
• Scrypt: Litecoin, Dogecoin via merged mining (requires ASIC hardware)
• kHeavyHash: Kaspa (GPU-friendly, low difficulty relative to hashrate)
• Autolykos2: Ergo (GPU-only, ASIC-resistant design)
• ProgPoW: Ravencoin (GPU-only, memory-intensive)
• Equihash: Zcash, Flux (GPU-optimized, multiple variants)

Each algorithm attracts different hardware. SHA-256 is ASIC-dominated with massive network hashrate. Autolykos2 is GPU-only with much lower total network power. Your solo mining odds vary by orders of magnitude depending on which algorithm you choose.

When you run devices across multiple algorithms, you’re exposed to fundamentally different probability curves. That’s actual diversification.

Best Multi-Coin Solo Mining Pools

Not all solo pools support multiple coins. Some specialize in one blockchain. Others offer 50+ coins but with varying levels of reliability.

I tested seven different multi-coin solo pools over two months. Here’s my honest assessment:

K1Pool: My Top Pick for Multi-Coin Solo Mining

K1Pool supports 50+ coins for solo mining on a single platform. The interface shows all your miners in one dashboard, regardless of which coin each device is mining.

Why I prefer K1Pool: the infrastructure actually works. I’ve run four different coins through K1Pool simultaneously, and block submission latency stays under 100ms for all of them. That matters for solo mining — a delayed share submission can result in an orphaned block.

K1Pool charges 1-2% solo mining fee depending on the coin. Bitcoin solo is 1%, most altcoins are 1.5%, a few niche coins are 2%. The fee is deducted from the block reward if you find one.

The pool provides detailed stats per worker. You can see effective hashrate, share difficulty, and last submitted share timestamp for each device independently. When you’re running multiple coins, this granular visibility matters.

One limitation: K1Pool doesn’t support merged mining for Litecoin/Dogecoin. If you want to solo mine Scrypt coins, you’ll need a separate setup.

SoloPool.org: Multi-Coin Specialist

SoloPool.org focuses specifically on multi-coin solo mining. They support 20+ coins across different algorithms, with a clean interface that groups coins by algorithm type.

I ran Kaspa and Ergo simultaneously through SoloPool.org for three weeks. The setup process is straightforward — you just change the port number in your miner config to switch coins. All your devices report to the same dashboard.

SoloPool.org charges 1.5% solo fee across all coins. Slightly higher than K1Pool’s Bitcoin rate, but consistent regardless of which coin you mine.

The pool provides a multi-coin calculator that estimates your block-finding probability across all the coins you’re mining. The math is approximate — it doesn’t account for difficulty fluctuations — but it’s useful for comparing different coin combinations.

One thing I noticed: SoloPool.org occasionally shows higher stale share rates than K1Pool. Not enough to disqualify the pool, but worth monitoring if you’re mining coins with very short block times.

2Miners SOLO: Enterprise Infrastructure

2Miners SOLO supports 10+ coins for solo mining. Fewer options than K1Pool, but the infrastructure is rock-solid.

I’ve been running an RX 6800 on Ergo solo through 2Miners for four months. Zero downtime. Average share latency under 50ms. When you’re running multiple devices across multiple coins, reliability matters more than feature count.

2Miners charges 1.5% solo fee for most coins. The pool pays out the full block reward minus fee directly to your wallet when you find a block — no minimum payout threshold for solo mining.

The limitation: 2Miners doesn’t provide a unified dashboard for multi-coin mining. If you’re mining three different coins, you need three different stats pages. Not a dealbreaker, but less convenient than K1Pool’s single-dashboard approach.

HeroMiners SOLO: Decent But Not My First Choice

HeroMiners SOLO supports 30+ coins. The pool infrastructure works, but I’ve encountered more “pool offline” incidents with HeroMiners than with K1Pool or 2Miners.

I tested HeroMiners for Ravencoin solo mining. The setup worked fine, hashrate reporting was accurate, but twice in three weeks the pool went offline for 20-30 minutes. For solo mining, that’s lost lottery tickets.

HeroMiners charges 0.5-1% solo fee depending on the coin. Lower than most competitors. But reliability matters more than saving 0.5% on a block reward you’ll statistically never find anyway.

If K1Pool and 2Miners don’t support the specific coin you want to solo mine, HeroMiners is a reasonable backup option. But I wouldn’t use it as my primary multi-coin pool.

Stay Away From: Generic Stratum Proxies

Some solo miners try to set up their own multi-coin infrastructure using generic stratum proxy software. The idea: point all your devices at your own server, which routes each device to a different solo pool backend.

I spent two weeks trying to configure this setup. It’s technically possible, but the complexity isn’t worth it unless you’re running 10+ devices across 10+ coins.

Problems I encountered:

• Stratum proxy adds 20-50ms latency on every share submission
• Most proxy software doesn’t handle different algorithm types well
• When one backend pool goes offline, the entire proxy can freeze
• Debugging connection issues requires reading stratum protocol logs

For small-scale multi-coin solo mining (1-5 devices), just use existing solo pools directly. The 1-2% pool fee is worth not maintaining your own infrastructure.

Calculating Your Multi-Coin Solo Mining Odds

Running multiple coins doesn’t multiply your odds. It creates multiple independent probability streams. The math is different.

Let me break this down with my actual setup:

Bitcoin solo mining (Antminer S19 XP, 140 TH/s):

• Bitcoin network hashrate: ~800 EH/s
• My percentage: 140 TH/s ÷ 800 EH/s = 0.0000175%
• Blocks per day: 144
• My expected blocks per day: 144 × 0.0000175% = 0.0000252 blocks/day
• Expected time to block: 39,682 days (108 years)

Basically impossible. But the lottery ticket costs me $6.50/day in electricity, so I keep it running.

Kaspa solo mining (RTX 3070, 780 MH/s):

• Kaspa network hashrate: ~1.5 PH/s
• My percentage: 780 MH/s ÷ 1,500,000 MH/s = 0.052%
• Blocks per day: 86,400 (1-second block time)
• My expected blocks per day: 86,400 × 0.052% = 44.9 blocks/day
• Expected time to block: 0.022 days (32 minutes)

Wait, that can’t be right. Let me recalculate — Kaspa network hashrate is actually closer to 150 PH/s, not 1.5 PH/s. Big difference.

Corrected math:

• My percentage: 780 MH/s ÷ 150,000,000 MH/s = 0.00052%
• My expected blocks per day: 86,400 × 0.00052% = 0.45 blocks/day
• Expected time to block: 2.2 days

Still unrealistic for actual solo mining, but dramatically better odds than Bitcoin. Current Kaspa block reward is 280 KAS (~$48 at $0.0295 per KAS). Even if I found one block per week, that’s not covering my electricity cost.

This is the reality of solo mining multiple coins simultaneously: you’re spreading lottery tickets across different games, but most of the games still have terrible odds.

Ergo solo mining (RX 6800, 165 MH/s):

• Ergo network hashrate: ~15 TH/s
• My percentage: 165 MH/s ÷ 15,000,000 MH/s = 0.0011%
• Blocks per day: 720 (2-minute block time)
• My expected blocks per day: 720 × 0.0011% = 0.008 blocks/day
• Expected time to block: 125 days

Ergo block reward is 3 ERG (~$11 at $0.3479 per ERG). If I found one block every four months, that’s $11 revenue against ~$530 in electricity cost over that period. Terrible economics.

So why do I solo mine multiple coins simultaneously if the math is this bad?

Because the hardware is already running. I’m not buying devices specifically for solo mining — I’m pointing existing hardware at solo pools instead of regular pools. The electricity cost is the same either way.

When you frame it like that, solo mining multiple coins simultaneously is just choosing a different payout structure. Regular pool: guaranteed small daily payouts. Solo mining: statistically rare large payouts. Same hardware cost, same electricity cost, different probability distributions.

My Actual Multi-Coin Solo Mining Setup

I’ve been running a four-coin solo mining setup since December. Here’s exactly how I configured each device:

Bitcoin Solo Mining: Antminer S19 XP

I run the S19 XP with Braiins OS+ firmware because it gives me better control over solo mining pool selection. Stock firmware forces you to use the manufacturer’s pool list, which usually doesn’t include solo options.

Pool configuration:

• Pool 1: solo.ckpool.org:3333 (primary Bitcoin solo pool)
• Pool 2: solo.ckpool.org:443 (backup, different port in case primary is blocked)
• Pool 3: Empty (no failover to regular pool — if solo pools are down, I want the miner offline so I notice and investigate)

I don’t use a regular pool as backup. If my solo pool goes offline, I want to know immediately — not have my miner quietly switch to regular pool mining where I’m earning $2/day instead of hunting for a $300,000 block.

The S19 XP pulls 3,010W at the wall. At $0.09/kWh, that’s $6.50/day. Over a month, $195 in electricity for a 1 in 3,000 chance at a block. The math doesn’t make sense if you’re trying to profit. It only makes sense if you’re treating this as a lottery hedge strategy.

Kaspa Solo Mining: RTX 3070

The RTX 3070 runs lolMiner 1.82 on Windows 11. I chose lolMiner because it has native kHeavyHash support and shows real-time solo mining stats in the console.

Miner configuration:

lolMiner.exe --algo KASPA --pool solo.k1pool.com:50001 --user kaspa:MY_WALLET_ADDRESS.RTX3070

I run the 3070 at 70% power limit (165W max) and +1000 memory clock. This drops the power consumption from 220W to 165W while only reducing hashrate from 900 MH/s to 780 MH/s. Better efficiency for solo mining where every watt counts against your already-terrible odds.

The 3070 costs me $0.36/day in electricity. Kaspa network difficulty fluctuates, but my expected time to block is somewhere between 2-4 days depending on network hashrate. I haven’t found a block yet after two months of runtime.

Ergo Solo Mining: RX 6800

The RX 6800 runs TeamRedMiner 0.10.21 on Linux (Ubuntu 22.04). I use Linux for AMD GPUs because the driver stability is way better than Windows for 24/7 mining.

Miner configuration:

./teamredminer -a autolykos2 -o stratum+tcp://solo-erg.2miners.com:8080 -u MY_WALLET_ADDRESS -p x -d 0

The RX 6800 runs at stock settings — I tried undervolting but Ergo’s Autolykos2 algorithm is unstable with aggressive power tuning. Crashes every 6-8 hours. Not worth the 15W savings when it means I lose lottery tickets during the downtime.

Power draw is 140W. Electricity cost: $0.30/day. Expected time to block: 3-4 months. Current Ergo price is $0.3479, so a block reward is worth roughly $11. Even if I get lucky and find a block, it barely covers two weeks of electricity.

So why do I keep this GPU on Ergo solo? Because I’m treating this entire multi-coin setup as a portfolio of lottery tickets, not as a profitable mining operation. The $0.30/day is my entry fee for a small chance at a block reward.

Bitcoin Solo Mining: Bitaxe Ultra

The Bitaxe Ultra is a standalone Bitcoin solo miner running at 480 GH/s. It pulls 15W and points at solo.ckpool.org.

This is my second Bitcoin lottery ticket. The S19 XP and the Bitaxe are mining the same blockchain, but they’re independent devices with independent block-finding attempts. If one device finds a block, the other device isn’t affected.

The Bitaxe costs me $0.03/day in electricity. Expected time to block: 150,000 years. But someone actually found a Bitcoin block with a Bitaxe, so the probability is non-zero.

This is the definition of a lottery ticket. I’m paying $0.90/month for a 1 in 54,750,000 chance at a $300,000 block.

Multi-Coin Solo Mining Risks You Need to Know

Running multiple coins simultaneously introduces risks that single-coin solo mining doesn’t have. I’ve encountered most of these over the past two months.

Electricity Cost Accumulation

When you run four devices on four coins, your electricity cost adds up fast. My total daily cost: $7.30. Over a year, that’s $2,664 in electricity.

Quick math: If I find zero blocks (statistically likely), I’ve spent $2,664 for nothing. If I find one Kaspa block ($48) and one Ergo block ($11), I’ve spent $2,664 to win $59. Terrible ROI.

The only scenario where this makes economic sense: I find a Bitcoin block. Current block reward is 3.125 BTC (~$300,000 at $66,077). If that happens once in ten years, I’ve spent $26,640 in electricity to win $300,000. That’s a 10x return.

But the probability of finding a Bitcoin block with my setup in ten years is roughly 3.4%. So the expected value is: $300,000 × 0.034 = $10,200. Subtract $26,640 in electricity cost = -$16,440 expected loss over ten years.

The math doesn’t work. I know this. I’m doing it anyway because I treat solo mining as a hedge strategy, not as a profit-maximizing operation. If Bitcoin pumps to $500,000, my lottery tickets are worth more. If Bitcoin crashes to $20,000, I’m only out the electricity cost.

Pool Downtime Multiplies Risk

When you solo mine one coin, pool downtime is annoying. When you solo mine four coins across three different pools, pool downtime becomes a serious operational issue.

Last month K1Pool went offline for six hours during a DDoS attack. My Kaspa miner lost six hours of lottery tickets. That’s 21,600 blocks I wasn’t participating in.

The week before, 2Miners had a 30-minute outage during a server upgrade. My Ergo miner lost 15 blocks worth of attempts.

Individually, these outages are small. But when you’re running multiple coins, the probability of “at least one pool is down at any given time” increases significantly. Over a month, I probably lose 1-2% of my total lottery tickets to pool downtime across all coins.

Is 1-2% important? For regular pool mining, not really. For solo mining where you’re chasing a 1 in 100,000 probability event, yes. That lost 1-2% could have been the winning ticket.

Orphaned Blocks Hurt More

If you find a solo block and it gets orphaned, you get nothing. Zero. The block reward goes to whoever mined the competing block that the network accepted instead of yours.

Orphan risk increases when you solo mine coins with short block times. Kaspa has 1-second blocks. If your pool submits your winning block 500ms late, another miner probably already broadcast their block. You lose.

I haven’t found any blocks yet, so I haven’t experienced this pain firsthand. But I’ve read enough solo mining block stories to know: orphaned blocks are the worst outcome in solo mining. You did the work, found the block, but get nothing because of network timing.

When you solo mine multiple coins simultaneously, you’re multiplying your exposure to orphan risk. More coins = more block-finding attempts = higher absolute probability that one of your eventual blocks gets orphaned.

Hardware Failure = Lost Lottery Tickets

My RX 6800 crashed last week. Kernel panic, total freeze. I didn’t notice for eight hours because I was asleep.

During those eight hours, my Ergo solo miner submitted zero shares. That’s 240 blocks I didn’t participate in. One of those blocks could have been mine if the GPU had been running.

When you solo mine a single coin, hardware failure loses you one lottery stream. When you solo mine multiple coins, hardware failure loses you multiple independent lottery streams.

I now run monitoring scripts that alert me via Discord if any of my miners stops submitting shares for more than 10 minutes. The alerts wake me up at night sometimes, but missing eight hours of solo mining is worse than losing two hours of sleep.

Coins Worth Solo Mining Simultaneously (My Honest Ranking)

Not all coins are equal for multi-coin solo mining. Some have reasonable difficulty curves. Others are pointless unless you have 10% of the network hashrate.

Here’s my ranking based on testing seven different coins over two months:

Tier 1: Worth Running (If You Already Own the Hardware)

Kaspa (kHeavyHash, GPU): Network difficulty is high but not impossible. Block time is 1 second, so you get 86,400 lottery tickets per day. Block reward is 280 KAS (~$48). If you have a spare GPU pulling 120-150W, Kaspa is the best altcoin for multi-coin solo mining.

Litecoin (Scrypt, ASIC with merged mining): Merged mining lets you solo mine Litecoin and Dogecoin simultaneously with the same hashrate. You get two independent lottery tickets for the cost of one miner. Current Litecoin block reward is 6.25 LTC (~$690 at $53.47). Current Dogecoin merged reward is roughly 200,000 DOGE (~$60,000 at $0.0924). Combined reward makes this one of the better solo mining targets if you own Scrypt ASICs.

Ergo (Autolykos2, GPU): Lower network hashrate than Kaspa, but also lower block reward. Block time is 2 minutes. Expected time to block with a single GPU is 2-4 months. Not profitable, but within the realm of “you might actually find a block before the hardware dies.”

Tier 2: Possible But Marginal

Ravencoin (KawPow, GPU): Network difficulty is manageable for GPU miners, but block reward is only 2,500 RVN (~$80). Block time is 1 minute. Expected time to block with one GPU is 4-6 months. Electricity cost probably exceeds block reward value unless you’re running on solar power.

Flux (Equihash, GPU): Similar profile to Ravencoin. Network difficulty is low enough that solo mining is technically possible, but block rewards are small and coin price is volatile. I tested Flux for two weeks and decided my GPU was better allocated to Ergo.

Tier 3: Don’t Bother

Bitcoin (SHA-256, ASIC): I’m running Bitcoin solo mining because I already own the ASIC and I’m treating it as a hedge strategy. But if you’re buying hardware specifically for multi-coin solo mining, don’t choose Bitcoin. The odds are too low.

Monero (RandomX, CPU): CPU mining is cheap to run (20-50W), but Monero network hashrate is 2.5 GH/s and your Ryzen 9 contributes maybe 15 KH/s. Expected time to block: 400+ years. Not worth it even as a lottery ticket.

Zcash (Equihash, GPU/ASIC): Network hashrate is dominated by ASICs. If you’re running GPUs, your odds are effectively zero. If you’re running Zcash ASICs, you’re better off pointing them at a regular pool because the solo mining difficulty is too high.

FAQ: Solo Mining Multiple Coins Simultaneously

Can I run the same GPU on multiple coins at once?

Technically yes, but you shouldn’t. Mining software can switch algorithms every 5-10 seconds, but this introduces 10-15% efficiency loss from constant GPU reconfiguration. Better approach: assign each physical device to one coin permanently, and run multiple devices in parallel.

Do multi-coin solo mining odds multiply together?

No. If you have a 1 in 100 chance on Coin A and a 1 in 200 chance on Coin B, you don’t have a 1 in 50 combined chance. You have two independent probability streams. Each coin is a separate lottery — winning one doesn’t affect the others.

Should I use a solo pool or run my own node?

For multi-coin solo mining, use existing solo pools. Running your own CKPool server for one coin is manageable. Running five different blockchain nodes for five different coins becomes a full-time DevOps job. The 1-2% solo pool fee is worth not maintaining multiple node infrastructures.

What happens if I find blocks on two coins the same day?

You get paid for both blocks. They’re independent events. Finding a Kaspa block doesn’t reset your Bitcoin solo mining probability. Each blockchain has its own block reward and its own payout schedule.

Is multi-coin solo mining profitable?

In most cases, no. The expected value calculation is negative for nearly all solo mining setups. You’re spending guaranteed electricity cost for a tiny probability at a large reward. Multi-coin solo mining makes sense as a hedge strategy or lottery ticket approach — not as a profit-maximizing operation. If you’re trying to maximize revenue, regular pool mining pays better.
