We mostly do it for fun or experiment like talking on this forum... do you get any money from it ? no, it's just for the fun.
I like making money.
I don't like to lose money.
IF i have a hobby that can make money, that's much more fun then a hobby that loses money, no?
i mean, it's basic math.
people dropping 10Grand on machines that won't ROI?
or 200USD on machines that won't ROI?
if that's fun, well. enjoy donating money to hardware companies, i'm sure they appreciate it.
no, you want to make easy money
mining is braindead simple these days so of course there is low ROI unless you gots the brains to make your ASIC chips and boards from scratch then you make ROI or perhaps you just need to get your pre-order scam going..
scamming is a hobby too
