I have been using f2hash for the past 2 months. So far, I can say its a pretty good site. Its quite simple to start immediately and anyone can get going in a matter of minutes. They have mining facilities in the tropics and they use solar energy to power their equipment.
The return on investment is short and the payments are quite steady. I would suggest you use crypto wallet as a withdrawal option since it's instant, withdrawing to bank took about me about two days to get the funds.
