At the end of the day, after 5 months of inactivity Revolut finally contacted me telling that they are closing my account due to their "internal policy" with no detailed explanation. Within next 2 months they returned about 80% of my money back to my card (that was initially used for topping up Revolut account) and to my account with another bank (asking me to provide a bank statement with valid account details). No more deals with this fintech Revolut!!!
Reading other review only, I would say Revolut is one service people should try to avoid at all costs. If there is no other option. Then don't trade at all.
I tend to avoid such service and instead opt for p2p crypto marketplace platform such as localcryptos if I want to instantly buy or sell BTC and other altcoins
