[Decoded]

Hey guys, id like to know what the best pool in terms of profitibilty is.

What's the:

- Most profitable pool if you spend $100 on cloud mining/mining hardware

- Most profitable pool if you spend $500 on cloud mining/mining hardware

- What's the best average ROI percentage? Do I get an ROI faster with a bigger investment or a smaller one?

- Most profitable pool if you spend $1000 on cloud mining/mining hardware

AFAIk on cloud mining, you can not choose the pool , for example on hashnest they point at antpool if i'm not mistaken

as it is right now it seems that s5 deliver a faster roi, taking into account that your electricity is very cheap
