The regulation of cryptocurrency is going to happen whether we like it or not.
How far the regulation goes will be based on the central banks and the government. The movement into crypto is a major threat to the power of central banks and government which is why there is so much regulations being release for it.
The government and central banks in most case are the controllers of the exchange rate; this is done through the change in supply of money or interest rate. Cryptocurrency is something they cannot control as the currency is mined and they cannot control the pricing, which is why they are worried.
Even with regulations though, it is expected that crypto will be growing in the next five years. The reason is because IBM invested a lot of money to teach companies including banks about the benefits of blockchain and with their understanding, they could find use or better control crypto.
