Hello Guys,
We have a new "promising" cloud mining site called Suanlitou.com
It offers open-ended contract which I do not prefer (We cannot know how long it is going to be available)
Unfortunately it doesn't contain free trial but it has referral program
Its Est. Roi is 437 days, which I find too long.
If you want to check
