i agree a pc can not mine btc well - i have a 4core 2gpu rig only capable of 600h/s now.
years ago this same pc could make me $1/day in btc, now I'm lucky to get 30¢/day
my plan is to mine 100 btc just so i can test how minergate withdraw works to my copay wallet,
then i'll find out what other ecoin mines well on my pc, but can still be converted into btc later.
copay lets me convert btc into amazon gift card credit, so it's a nice anonymous way to cash out.
