China just made statements cracking down on mining/trading, the US proposed new reporting requirements for transactions, the concern of crypto being used for tax evasion and illegal activities, the Bank of England governor recently said bitcoin has no value, European officials have often made negative statements, and there is always talk of bans in India. It was just reported on the news that Hong Kong is going to announce a ban for retail trading of cryptocurrency.
It's obvious that countries haven't considered bans in the past because they didn't consider bitcoin to be a threat, and it gets harder to ban the longer they wait because of the negative effects on their country, but the possibility remains. Also even if it were not banned, governments can monitor all activity because basically everyone uses centralized exchanges and the blockchain is public. They can tax it at whatever rate they decide to. It is just not conceivable that ordinary people are going to install applications on rooted phones to be able to continue to use bitcoin in the presence of a ban.
So what would the future trajectory of the world look like after that? I guess the price would fall precipitously, probably under 5000 USD or more likely 1000. Are people still going to want to hold it when the government can always come after them? I don't see how any small underground activity like paying your hairdresser in crypto, or even sending money to family/friends internationally is going to be able to sustain the viability of bitcoin, nor how the vast majority of the population can be convinced to use it in the face of government FUD.
One thing that does not seem to a be a concern is mining, because even if governments outlaw and can find ASICs and farms, the mining can always shift to use less electricity, fewer ASICs, etc.
I think the market price would say more than enough about what you are thinking. This undoubtedly is something that we all are struggling through and thinking all day but at the same time after the big dump we did see that the price climbed up very fast. Yes it may not be equivalent to all time high but it's still holding.
China can ban Bitcoins they are trying to implement their own crypto which is nothing but fiat and people will be Forced to go that side.
At the same time Elon musk and other business men are doing what business men does ! They are trying to pull the price down so that they can buy low and sell high.
We see such problems every once in a while but I do think that you have to understand that it can go without any county of any government. Complete ban is not only impossible but not needed. There will always be people and countries supporting Bitcoins and government can't sentence thousands of millions of people to jail because they used Bitcoins in the same day, they won't have enough cells for that , haha so just keep using it and fight for it.
Ban is only implemented if the public decides to go with it.
