Hello, I finding website where I can buy bitcoins with credit cards without registration. Only enter e-mail and bitcoin wallet.
there is no such place because if any service decided to do that, they are going to get scammed out of lots of money in less than a week. because anything fiat related and with credit cards can be exploited and bitcoin has no charge back to fight these scams.
one of them is stolen credit card scam, and that is one of the reasons you have to provide your identity.
