Trading isn't illegal. You just can't use your bank account for anything crypto related. Likewise, crypto businesses won't be given access to bank services either. Peer-to-peer is essentially the only way to go from this point and it's still perfectly legal. For your situation specifically: you can use localbitcoins but you can't cash out to your bank account (or you can, but your bank might close it).

It also has to be noted that this central bank ban is not permanent yet. There's still a hearing scheduled on July 20 so it's possible for it to be lifted then. Cross your fingers, there's still hope.
