I really don't understand, it's already 2019 and people are still believing that cloud mining is still one way to earn and the best way to invest your money??? *face-palm*..
Actually it was not scam, but when the mining fee got higher and the price of bitcoin getting down.. So yeah..
I got like 3 times of my investment back in 2017 on hashflare.
But now, every cloud mining are almost scam

I never invested in cloud mining business because i feel it is sort of a scam. More of the sites collect the money from the people in name of mining and they exit when they got enough money.
On the other site, even if the site do not exit, the change in bitcoin prices make it difficult to get profit out of it.
