https://youtu.be/PyQEf_LlbUk Im not joking watch this video, with 3000 mh/s he earns 0.0172
BTC a day, calculate with 15gh/s = around 0.06
BTC a day. Ok if Im wrong, but with 15gh/s should still earn around 0.02 - 0.03
BTC a day i think.. Why people buying antminer with TH of power? because they want to make lots of
BTC in one day.
Oh, you got the idea from the repository of the sum of all human knowledge, Youtube!! Doesn't anyone look at the dates of things anymore?
When the BFL Jalapeno's started trickling out when they were new, 4 or 5 years ago, they may have made that much BTC, but, not anymore. Now the entry hash rate is in the range of 8 to 14 THs that doesn't even approach the numbers your talking about.
Don't waste too much time with Youtube, always exercise a bit of common sense and research to corroborate what other sources claim.
Good luck.
