you can't actually transfer your crypto out, it's just. a. gimmick. There's no ltc btc wallet to work with.
Before you can actually trade cryptocurrency, you have to refer at least 3 people to open accounts with Revolut. Personally, I have already referred more than 3 friends but for some reason the cryptocurrency trading feature is still locked for me.
the app is easy to use, but cryptos are a bit difficult to find. the prices also seem to be high.
