Last past months Sri Lanka's Main Bank (Bank of Ceylon) was banned cryptocurrencies in Sri Lanka. What do you think is the reason for that ?

If some nation want to progress, they will have to accept crypto.
Agree with your comments. All countries that banned Bitcoin is countries poor and small. They want to develop, but they think that Bitcoin and cryptocurrency will make their economies go down. But I hope in the future, these countries will have positive thoughts about Bitcoin
How unfortunate. They banned bitcoin because they lack the knowledge about its capbilities or because of the news and articles about users being scammed since there are still scammers in the community.
