Well, I rent hash power on nicehash and I spend 0.01 btc. after spending all of it, I only got 0.0004 in return. is renting hash power profitable? then why many people still renting hash power on them. am I doing something wrong?
Your own example tells you everything you need to know, the best way to get bitcoin in my opinion is to personally mine a profitable altcoin and convert or just buy the bitcoin itself
if you will rent mining rigs with bitcoin to mine bitcoin itself is not profitable
difficulty rise and there also so a lot of competitor
but if you will use the rigs you rent to mine alt
maybe you can make profit or altleast break even
