Hey there, I would like to invest into bitcoin, any good website to earn good money/btc ?
I see no advantage in cloud mining. The best you can do is buy BTC with low price and sell with high price.
hashnest S5 is still OK to invest
you should try
Hashnest SEEMS to be trusted right now, they may just run away in the future. Hashnest is still quite in the unprofitable range, did you factor in the possible difficulty increase and maintainence fees? When you add these together, it would most probably be not profitable.
