Alas! Another cloud mining scammer
Alas! Another cloud mining scam. It might look legit, but, as you progress you'd realize that they'll stop crediting the BTC to your wallet, over and above they may deduct in the name of management fee, despite of you paying the amount. You'll never make profit out of the contract you've bought for 100% sure, also you may loose your money (principal amount) significantly... instead just do your own mining by investing in graphics card / asic miners, that would be better, those things are very much and under your control and will be profitable as well after a stipulated period. Bitfufu is a very legit scam, by the time you realize it is you might loose your savings. Better stay away!
