These days, a lot of countries are actually being more accepting of bitcoin than they ever were before. I feel that it’s more likely for a country to accept bitcoin now than to ban them. But hypothetically your country bans bitcoin, will you still use bitcoin?
It all depends on what you mean by accepting and banning bitcoin.
Banning it as a means of payment? - most countries will probably choose this.
Banned on ownership/storage? - I don't think it will be widespread if it happens. On the other hand, how will governments know what you own? No way. Until you show it yourself.
Banned on investing? - I don't think there will be such a ban either (with the exception of some countries), because the government will want a percentage of it in the form of taxes.
It should also be added that bitcoin was created as an alternative to the current financial system, which means that whatever happens in the "traditional system", this doesn't affect the
BTC-system. In other words, it exists in parallel, which means that no bans can affect it.
I asked this question to myself then realized that using bitcoin even without the approval of the government is exactly what bitcoin is for. I will only be realizing bitcoin’s full potential, am I not? This is what bitcoin’s true purpose is. Should you be scared to use bitcoin to its fullest extent?
Everything will depend on the legal framework of the country you are in.
If someone kept using bitcoin despite a ban, will he be considered brave? Or will he be considered suicidal? Especially if the government imposes strict bans that could lead you to being jailed simply for using bitcoin.
These questions can be addressed to anything that is prohibited by law.
Do anything at your own risk.
What is surprising and terrifying is that bitcoin will potentially be put on a par with "traditional" items and substances prohibited by law.
