Bitcoins per Month (Profit)
Earning less than a dime per month, Avalon Nano 3 will give you about $1 per year.
Power Consumption
Slightly more electricity will be used by this miner via your computer but can hardly be noticed unless you use it with an unplugged laptop. That will surely consume your battery fast!
Price
For just about $20, you can buy Avalon 3 in eBay, the cheapest place to buy.
Setup
Setting up your miner with mining software is needed, as well as deciding on a Bitcoin mining pool.
Temperature
Temperature will be the least of your concerns with any type of USB miner. It won't get hot as much as you need a fan.
Power Supply
This is just plug n' play so no need for power supply. Plug it into your computer’s USB port and start mining!
