As someone having a GBP, EUR and a BGN currency bank accounts, transferring money from one to the other is really painful and is currently solvable at low cost only by some digital banks - Revolut, n26, Transferwise. Also interesting that the legislation was pushed by a Bulgarian EMP - Eva Maydell, where fees seems to be the highest.
