Tried with blockchain however it isnt accepting my payment. To do transaction more than £50 it says I have to do it via bank transfer. But it wants some details such as photo of some id such as driving license. Is this safe to provide?
If You don't want to use any centralizes wallet then go for decentralized one(one that provides private key) lEg: Bitcoin Core. Safe and reliable.
I think it will solve all your problem.
