I know their S9's are profitable and I actually hold some but it's not profitable enough for me. Cloud mining is just for fun for me. my physical possessions of rigs outweighs my cloud investment by magnitudes.
If the don't pay out because of high electricity costs in cloud, why do you think that they will pay out for you? Do you have access to free or very-very cheap electricity?
I hope their S7 would go into redemption soon. That's why I want to know if anyone here has experience in receiving redeemed S5's.
The redemption period will be announced when the maintenance fee/payout ratio goes to 100%.
For the redemption miners will be the used machines but the factory will at least test them to make sure they are running before delivery to users.
Hope you understand those miners would not be completely new ones.
