I have some experience in cloudmining. for now, it seems like I want to monitor the development of this site in advance. however, cloudmining is a bit risky. well, we can't prove the seriousness of the site within a few months. so, I will only see this development for a while.
Might be wise to watch how they develop or just start with a small investment.
