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. Before devs will be able to launch a new cryptocurrency, they're going to need governments' approval. Otherwise, they could face serious consequences in the long run.
Thoughts?

Today it is also seen that devs are anonymous, so they don’t necessarily say who they are. Nevertheless, it decreases trust from users.
On the other hand, there are countries where laws are very unstrict, so developers can work from there.
You noticed correctly that authorities were not very happy with crypto, that is why they are trying to replace it with digital state currencies, but it is completely another story.
