Hi guys, I was trying to get information about this company before investing... but 53 pages is too much to read now. I would like someone to answer 2 basic questions:

1- Is Hashflare a legitimate company? Do they have mining proofs?

2- I have seens that they allow to buy hash, for Scrypt, Ethereum, Sha-256 etc... Which one is the most profitable and what's the roi?

Thanks in advance
