Is hashpower.braiins.com working properly?
Can you recommend other legitimate cloud mining providers?
Thanks.
I checked them out, they do not actually claim that they are cloud mining providers, rather they are listed as a hashrate marketplace where you buy mining power for use in the supported pools or for solo mining.
Besides, it is still listed as beta. Inquire if you can be rewarded as early testers without committing money.

Read what people said above about cloud mining.
If I may ask, are you so passionate about cloud mining or you are looking to make some profits. If the later is the case, you can follow Rikafip advice.
