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?

I don't think there will ever be such restrictions. In order to suffer the consequences of creating new coins, governments would have to make cryptocurrencies illegal. Governments can block development by hindering cryptocurrency trading, but will never penalize developers for creating a new coin or token.
