Avalon Nano 3
The first-generation Nano. Same 140W envelope as the 3S but a third less hashrate, which makes it a poor buy new — the 3S is the direct replacement and is barely more expensive.
Typical street price, excluding shipping and duties.

What it costs, what it might win
Running costs across the site use this rate. The default is a typical household tariff — check your own bill for the real number.
The odds, honestly
At the current network difficulty of 1.262e+14, a Avalon Nano 3 is expected to find a block roughly once every 4.3K years. That is an average across infinite attempts, not a countdown — a block could come tomorrow, or never.
If you pooled instead
Point the same device at a normal mining pool and you would receive the statistical average steadily instead of gambling on it: about $0.0000 a month, against $17.39 of electricity. At your electricity rate that loses money — every 201 sats mined costs $0.5712 in power. Buying the same BTC on an exchange would be cheaper.

About Canaan Avalon
One of the two large ASIC manufacturers. The Avalon Nano, Mini and Q lines are Canaan's consumer push: closed firmware and an app instead of a web UI, but proper industrial silicon, real warranties and usable waste heat.
