I also read that this morning that
Trump administration wants to regulate Bitcoin.
I think all governments will have to do that. They have no choice. The popularity and usage of Bitcoin is increasing. To ignore it even longer is negligent for governments. That's why I think that after the tax reform, other minor reforms will come, including the regulation of cryptocurrencies.
I think the reason this issue is mainly focused on Trump and his administration is because it is the US we are talking about. The US is admittedly the father of all nations because its involvement in basically everything that is going around the world greatly influences our respective governments and our future generation.
With this, all countries that have partnership with the US may adapt the same mechanism as that of the US. Of course, only if they have the capacity to adapt the same. But knowing the US, they always extend help provided you become their folly.
