Hasnest any moment we can withdraw the initial investment at any time, and the payments are in the moment they found the block
I'm confused now
If you're willing to trust hashnest you can always try them out. There are some things you should know though. One of them is that there are no guarantees. All that bullshit talk about lifetime contracts, guaranteed roi, thousands of happy clients and such are just ways to get more clients and rise confidence in this cloud mining system.
Truth is that you're giving your money to a business that can lose it or steal it. They can go out of business and you won't get your money back. It's risky with exchanges but even more with CM because you're keeping your money with them for a year or more. If you withdraw early you won't get any profit, that's why they're allowing you to do it. It's even better for them.
