Cloud mining, like GoMining, is the easy way to earn Bitcoin — you don’t touch any hardware at all.
Lottery miners are different. They’re small, real machines you plug in at home. They mine alone, not with a big team, which means you’re trying to find one whole block all by yourself. The odds are small, but if you win, the reward is big. These machines are also just plain fun if you like gadgets and want to learn how mining really works.
Here’s how the top picks compare.
Nerd Miner 2 — the low-cost starter toy
- Hashrate: about 250 KH/s (a small amount of mining power)
- Power draw: about 1 watt
- Best for: Beginners who want something cheap and fun to watch, not a real shot at winning
This little device plugs into a USB port. It shows Bitcoin’s price and mining stats on a small screen. Think of it as a fun toy that teaches you about mining — not a real investment.

Bitaxe Gamma — the efficient pick
- Hashrate: 1.2 TH/s (much more mining power than the Nerd Miner 2)
- Power draw: 15 watts
- Best for: Beginners on a budget who still want a real chance at mining a block
Bitaxe started the whole home-mining hobby. The Gamma model is small, quiet, and connects over WiFi.
Here’s the honest math on what a “real chance” actually means. The whole Bitcoin network is running at about 816 EH/s as of August 6, 2026. A single Bitaxe Gamma at 1.2 TH/s would need, on average, roughly 12,900 years of nonstop mining to find one full block on its own. If it ever does hit, the prize is real: today’s block reward of 3.125 BTC plus fees, worth somewhere around $200,000 at Bitcoin’s current price. That’s the lottery — brutally long odds, with a real jackpot if it lands. Spread out over time, the math works out to only a few cents a day in long-run average value, which is exactly why nobody should buy this expecting steady income.

Avalon Nano 3S — the next step up
- Hashrate: 6 TH/s
- Power draw: 140 watts
- Best for: People who want better odds without buying a giant mining rig
I mention this miner in my own beginner guide. It runs warm enough to help heat a small room in winter — a nice little bonus.

NerdQaxe++ Hydro — cooled with water
- Hashrate: 6 TH/s
- Power draw: 100 watts
- Best for: Hobbyists who want strong performance and don’t mind extra setup
This miner uses water to stay cool. That keeps it quieter than air-cooled machines with similar power. It also shows real-time Bitcoin prices right on its screen.

NerdOCTaxe — the top pick for odds
- Hashrate: 9.6–12 TH/s
- Power draw: 160 watts
- Best for: Serious hobbyists who want the best home mining odds you can get
This is the strongest home miner you can buy without moving into full industrial equipment. It has the most mining power of the group — and the highest price to match.
Running its full 9.6–12 TH/s against that same ~816 EH/s network (as of August 6, 2026), the expected wait to solo-find one block works out to somewhere between roughly 1,300 and 1,600 years, depending on where in that range your unit lands. That’s about 8 to 10 times better odds than the Bitaxe Gamma above — still an enormous long shot, but the best odds of any miner in this guide. The prize is the same either way: today’s 3.125 BTC block reward plus fees, worth around $200,000 at current Bitcoin prices.

How Crazy Are These Odds, Really?
Numbers like “1 in 4.7 million” are hard to picture. So here’s how one day of solo mining stacks up against other things people call basically impossible:
- Winning the Powerball jackpot with one ticket: about 1 in 292 million, each drawing
- Getting struck by lightning at some point in your life: about 1 in 15,300, over an 80-year lifetime
- Solo-finding a Bitcoin block with a Bitaxe Gamma: about 1 in 4.7 million, each day it runs
- Solo-finding a Bitcoin block with a NerdOCTaxe: about 1 in 500,000, each day it runs
These aren’t quite an apples-to-apples comparison — Powerball’s odds are per ticket, lightning’s is over a whole lifetime, and the miners’ odds are per day of nonstop running. But side by side, it’s a fair gut-check: even the strongest home miner in this guide has better odds each single day than winning Powerball does with one ticket. You’d just need a whole lot of days.
Ever Wonder What It Would Take to Skip the Odds Entirely?
Every miner on this list is playing the same lottery: hoping to find one whole block alone. Curious exactly how long those odds really are, and what you’d win if you beat them? I lay out the full math in Solo Bitcoin Mining, Explained.
Which One Should You Get?
Want the cheapest way to try mining? Start with the Nerd Miner 2. Want a real, but still small, chance to win without spending a lot? Most people pick the Bitaxe Gamma. Everything bigger than that just buys you better odds for more money — worth it only if you enjoy the hobby itself, not just the chance of winning. Always check the live price on Amazon before you buy, since prices change often.
One honest note: winning a full block with any of these machines is a long shot. That’s why it’s called “lottery” mining. If you want steady, more predictable rewards instead of a lottery-style bet, that’s what cloud mining through GoMining is for — I explain how that works in my free Bitcoin Beginner Blueprint.
