As crypto/Blockchain tech becomes more popular, mainstream banks and governments will be forced to take action against this emerging industry to stop its growth worldwide. They don't want to people to use crypto on top of Fiat, so we'll be seeing new tactics from said entities in order to destroy crypto for good. One of those tactics could be either banning people from trading crypto at a centralized exchange or simply prosecuting developers of a cryptocurrency project. I believe the latter option is much easier and effective for governments to put an end to crypto for good.
I don’t see that to be true. They don’t see cryptocurrency the way you think they see it. Yes there are some governments that sees cryptocurrency as a very bad thing and they always look for ways to stop people from making use of it, and they go to the extent of banning cryptocurrency mining facilities, and cryptocurrency exchanges to make it hard for those that would want to make use of cryptocurrency. And they will also close your bank account when they trace that your transaction has to do with crypto.
But that aside, there are many of them that view cryptocurrency as a big industry/business opportunity that’s yet to be explored, so they allow them to keep growing. It’s just like Coinbase has grown to be a big company in the United States to the extent debuting on Nasdaq list. So, I don’t think the government in most countries will try to stop developers.
