Please, could you recommend a site for investing in Bitcoin. I want a site that is safe and fast and that is verified or has many members. If you post some site, please tell me if you had any good or bad experience if you did try and invest trough that site.
I haven't bought BTC for a while, but my favourites were Coinbase and Bittylicious. Coinbase has higher fees but Bittylicious feels a little more risky. That said, I'm yet to have a bad experience from it
