Why is it so difficult to buy Dolz currency.
I assume you're using the oneclick wallet. Most banks will reject crypto currency, especially if international source. I had to call my bank and they had to waive the restriction and also go into the Visa system and waive it there. They did this while on the phone to monitor the transaction. You don't have to tell them you buying a porn card, just you're buying crypto to purchase a NFT (if you have to tell them what your buying).
I had a Mastercard that worked well, but for the last few weeks Wert was unable to process Mastercard transactions.
