My friend was mining for bitcoin with antminer's...but the dificulty went so up it wasn't profitable no more...so he bought GPU's and started making money again...he told me several times to get in "the bussines" but i didn't had the money at the time...in the end of may this year i got my first GPU miner and the profit was super...i got my investmen back in 3 months but then went down...prices of coin's were droping hard...sometimes i did not even cover my electricity cost...with today's price i'm making about 60$ profit with 9 GPU's...in my country electricty is very expencive...so this is my main problem...i'm searching how to reduce elec. cost...
"whattomine.com" is very good for getting info about which coin to mine, what is the profit,...
You said there is super profit in first 3 months and then it went down.
You did noting to your system and why its happens?
Is this Profit loss happens due to the higher number of miners in the system or what?
