Since January 1,2017 has anyone ever hit a block of bitcoin solo mining on a laptop with a usb miner like gekkoscience 2pac?
This could be life changing money for $100 investment
With the increase on difficulty level and increased in the numbers of miners using a much stronger Asic miner,
I think using a USB miner will not be profitable now a days.
Asic Miners has a speed of as much as 14.5 THs compared to USB miners 15 GHs. And you even need to have a
bunch of Asic miners for you to get a single block of BTC.
