The major governments of the world have for some time been laying the groundwork for their own national cryptocurrencies. Does that matter? Yes, it matters a lot. Bitcoin will be a direct competitor.
Why do they do this? To remain in financial control and to stop financial crime like whitewashing of funds from happening. Is it likely to happen? Yes, the US banned holding gold privately in the 1930's. So that the US government was to be a monopoly gold holder in the US.
There is a clear danger that the US, Europe, China, Japan and others will get togheter and flat out ban and even criminalize the usage and holding of Bitcoin. Resulting in after the ban, if you are cought using and holding BTC, you would get a huge fine or jail term.
The price of Bitcoin would get killed completely, you would be looking at Bitcoin below $1000.
How likely do YOU think this scenario is? Although you might say this is only speculation, IT IS A FACT that these countries are working on cryptocurrencies of their own.
very low. the crypto community is not criminals, and they are not doing anything illegal. maybe there will be a ban, but to impose the punishment only for the holder, that is a mistake. there will be many who protest about this issue. after all, crypto provides benefits for all, and if you look at it, isn't it more profitable for the government, if crypto / bitcoin is legalized but on the condition that they are taxed. there will be a lot of income they will get considering the marketcap for crypto is huge.
