There are many places that offer a crypto purchase service using a credit card, but it seems that many card companies in Korea often block this kind of transaction. Any of these problems in other countries as well?
Surely there will be countries like these. With the volatility of crypto and some scam attempt and reports for sure they are so prrcautious to accept and utilise the debit and credit card payment for this. There are some whose accepting but trust me, many still afraid of it that it could cause hacked or breach of system.
