Based on demand and the US decision many around the world have started the process of implementing their plans in the same way, resulting in it becoming a global store of value. The number of Bitcoin users is increasing day by day and the number of investors is increasing.
Bitcoin is a big asset to invest into now. When Nayib Bukele first took the first step to make bitcoin a legal tender in El-Salvador, it never made a lot of interest in the internet or the market reacting to that, but when the US government decided to do the same, the news spread everywhere so quickly that even the market reacted to it. That is the power of a developed nation over a developing one.
Bitcoin has long since after US announcement to use it as strategic reserve got more attention and people are now rushing to invest which has also helped in plummeting of the price to where it is today. It is a great thing to see the government exploring more ways to have Bitcoin as a store of value rather than just investment asset which big institutional investors use it for.
