In India, RBI had issued a notification banning banks/regulated entities from entering into transactions with entities that dealt with cryptocurrencies in 2018. All the banks then refused to service any crypto exchanges due to the notification. However, this was successfully challenged before the Supreme Court and which quashed the notification and thereafter dealing in crypto was made very smooth.
Recently, some banks were found quoting the quashed notification to refuse services to crypto exchanges. Therefore, RBI again issued a confirmation that its previous notification was no longer valid and that banks are allowed to provide services to crypto exchanges.
There are many nations that did that, or still doing that. In my nation it was illegal for banks to work with crypto companies as well, now there are 10+ local exchanges working with every single bank, and even doing 7/24 wire transfer which I can't do from my bank to another banks account for example, so I could basically send someone money from my local crypto exchange if I want to but can't send them from my regular bank (out of work hours), so they are very supported.
Basically each nation has the same time line, they first do not care, then they care but ban it until they understand what it is, then they let it be once again to see how it works, then they study a way they could make money from it (taxing) then they support it a lot so that they could make money. Not only crypto is a good thing for you, it is a good thing for your nation, India for example would be one of the best examples of that, you see in the future India will support it a lot.
