I saw this article today: https://news.bitcoin.com/singapore-regulatory-framework-cryptocurrency-payment-services/ about paying with cryptocurrencies in Singapore.
The central bank has finalized the new regulatory framework for payment services and they have included cryptocurrencies.
I think this is the future of banking and something that all countries should start doing.
The plus of making this change in the financial system is that there will be less money laundering and terrorism financing risks in the crypto world which is good for normal people that have hope and invest in online coins but bad for the ones that use the online coins for the reasons mentioned before.

What do you think? Is it a good idea to introduce cryptocurrencies in the financial systems of the world's countries?
