Also, they appear to be just another cloud mining scam / ponzi scheme.
If I'm thinking the right company this is essentially Bitmain's newest cloud mining operation, they just re-branded and launched under this branch as I believe their previous service was seeing dwindling sales/customer satisfaction. They are as legitimate as they can be for this type of service. Laughable at how lazy they were in creating their own banner.
They are definitely affiliated closely with Bitmain because I can log into Bitdeer with the exact same credentials as I have for Bitmain. I didn't even need to create an account. Also, the hash is legit. I have the option to switch to quite a few pools, and when I log into the pool, it shows my hashrate. However, it does suck that it appears they are using design elements for their banners which are stolen from someone else.
