So in short there is a 12% premium charged in my country
So I was thinking like in the old days I could purchase btc internationally via creditcard
Does anyone know any European or international platform offering such services??
Where are you from? You've got a few options like Coinbase, or Bitpanda for Europe. If you're willing to verify your identity as it looks like, it's probably better to use your bank account directly, or deal with other individuals P2P to eliminate those high fees.
