I know I was just wondering if I could have made profit in over 3 years or what the cheapest miners were
okay here is the deal you have 8.8 cent power that means profit is possible not certain possible.
under 5 cents and the right gear you make will money.
5 to 7 cents should make money
7 to 9 is the world of maybe.
the most efficient gear is from bitmain it breaks and breaks and breaks and breaks it also cost too much for you budget. 1000 to 1600
you next chance is avalon 721 or 741 it is reliable but cost about 880 usd for one.
no other gear is efficient enough to make money on btc at 8.8 cents.
so you are at the world of alt coins.
You might be able to build a rig for 300-400 usd mine a coin like xmr and make a profit,. would be hard. but may it could be done. a plus about this is your rig is a pc that can do other stuff.
