To be honest, it is impossible to prohibit Bitcoin, because users will find ways to access this currency, simply that Bitcoin has no borders and cannot be banned.
If its unabannable then why do you think that countries like india , china and many more have offically declared that bitcoin is banned on thier own country ?  The government cant ban bitcoin itself but it can ban the bitcoin related websites , trading sites or anything that is related to it (  i mean they can ban the acces with it )  they can also totally ban the offline exchange ir stores that supports bitcoin  .
Have you ever wondered why no country has not been able to ban Bitcoin and crypto completely despite declaring multiple bans so far? Do your research. The only way Bitcoin can effectively be banned is in 2 ways:
- If the miners stop mining completely and if trading halts completely due to which the entire market would collapse which will obviously not happen.
- The other way to effectively ban it completely is but shutting down the Internet completely which is also an impossible scenario.
This is why it BTC and crypto are here to stay no matter what anyone think of them.
