Gold and foreign currency reserves are held as the Federal Reserve of most of the country in the world to reduce inflation and maintain the balance of wealth. While most countries show gold and foreign currency holding as reserves the United States is taking its large economy to a stronger position by considering fuel oil and crude oil as reserves. Some of the new states that will be joined the plan consider Bitcoin as a strategic reserve along with gold and other valuable assets.
The US President signed a bill for the establishment of a Bitcoin reserve but I doubt if the country has bought a single Bitcoin. Only seized Bitcoin is in US custody. I am also aware that states like Texas, Arizona, and New Hampshire have signed the same bill but it has not been implemented.
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.
Even before Trump became president, Bitcoin was already a globally recognized store of value. Bitcoin adoption will keep increasing without a US policy on Bitcoin reserve. The coin doesn't depend on politicians to become popular.
