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
You are just playing lottery my friend, you are hoping to mine a block with a very underpowered computer and that is simply not going to happen, you are going to get more profits by simple selling that hardware and buy bitcoin with it, the time where you could mine with that equipment is over.
You are going up against odds worse than getting struck by lightning, or hitting the jackpot on a state lottery.
but as above suggests, you are hurting your opportunity cost by tying up your money in something with virtually no chance of roi. if you can do this at someone elses expense (power I mean), it STILL really wouldnt be worth it. You have the approximate snowball's chance in hell to hit this naturally. but it is possible, just good god almighty improbable that you will.
now if you sold that miner and saved that electricity, you could invest into an emerging, promising alt coin (not a shit coin!)
