I highly recommend members trade Hashrates only. Do not sell whole accounts. It can be very cumbersome.
How do you go about trading hashrates? I don't see an option for that in my account.
Private arrangements in forums. Then seller has to inform Hashflare through Support channels. So far Hashflare is supportive.
Selling or buying hashrates is okay. No issue so far.
But selling or buying whole accounts, it is an issue. I am having a problem with a transaction, Hashflare is doing what it could to ensure it is not a hacked HF account. Understandable.
