I have over 2 bitcoins saved in the website, https://bitrez.io. and 17 bitcoins in the other website:
https://hyperhash.io I tried to withdraw my bitcions but it does not work even though I upgraded to Professional Plan towice to withdraw my funds. I contacted the sites support 4 or 5 times but no one answered. Can anyone help me to withdraw my Funds or give advices?
Those both are really sketchy. And I had to guess I'd say you gain those bitcoins in no time, which couldn't been done even with a really massive mining rig.
Reconsider your choices - crypto is not a way to gain profits from air anymore, there is no way around it too
