Banks in Germany started to allow people to buy and sell cryptocurrencies this January 2020. I think other countries will do the same soon, Japan might be another country with such services. In the beginning, someone has to start something so others can follow suit.
What are the other countries where anyone legally can buy/sell cryptos at commercial centralized banks?
buying and selling bitcoin and other crypto currency is not a problem in my country. You can buy and sell directly using your atm card, not only that there are many other option for buying in my country even using remitances.
I hope it will also work with other country since it all working to us.
