I think that governments are afraid of Bitcoin. The main reason for this is the lack of centralized control over the processes. Governments are used to controlling fiat currencies, that`s why they don`t know, what to do with Bitcoin. Most governments have a choice: to legalize or ban Bitcoin. This decision determines the further influence of Bitcoin on the state.
Completely agree with you, mate. That is why China and other countries have acted against cryptocurrency exchanges, to stale Bitcoin's growth on the markets. Fierce regulations against ICOs and exchanges, will make it harder for Bitcoin to grow into a full-fledged mainstream cryptocurrency. But, despite everything that has happened against Bitcoin, the pioneer cryptocurrency has emerged stronger than ever with an ever-increasing price of $15k and above.
Since Bitcoin is a decentralized cryptocurrency, governments will have a hard time trying to stop its growth. However, because Bitcoin and many cryptocurrencies are traded on centralized exchanges, governments can stop, ban, or even regulate these exchanges to their own needs. Hence, more decentralized solutions would be needed to make the whole cryptocurrency ecosystem unstoppable. With the advent of decentralized exchanges, I'm sure that governments would have no choice but to completely legalize Bitcoin in the future. Just my thoughts
