Be careful
Be careful! Hashgains stopped ETH withdrawal from client wallets. I tried to transfer my ETH, which my mining plans mined for me in 1,5 years, the withdraw was paused and it is already a month since I can not withdraw the ETH. I wrote to support dozens of times, never got answer back. Client support is telling each time that I need to write an email, but it doesn't help. It looks like there are paying for the customer any more.
