An important reason for Bitcoin's popularity is that it has withstood the test of time. No digital currency has experienced so many ups and downs like it. It has been discussed many times around the world, and tenacity of its vitality also proves its value from the side.
Moreover, Bitcoin is the most widely-consensus digital cryptocurrency, and it has a strong international circulation. The total amount of Bitcoin is constant at 21 million, and it is halved about every four years. It is scarce. In addition, Bitcoin is a peer-to-peer transaction transmission, free from the intervention of various institutions, and can circulate around the world. You can send your Bitcoin to any corner of the world. Coupled with the fact that Bitcoin has higher returns than gold. Digital currency or encrypted assets represented by Bitcoin is the general direction of the development of the entire financial industry.
The great investor's enthusiasm over Bitcoin is based on its overall progress during last decade, it is proven only crypto asset that surpasses the expectation of investors and breaks the previous record highs. And bitcoin has been presented to the world to comply with the general trend of economic globalization.

I think the big mistake that Satoshi made was underestimating the popularity of Bitcoin and putting a hard cap of 21 million on it. The idea of stopping inflation with what looked like a huge number in circulation was great and certainly helped build the popularity in the early years, but it is now proving to be a bit impractical in some ways. Every day more and more Bitcoin gets lost - as we saw with John McAffee and Micrea Popescu who died suddenly, making large amounts inaccessible. While it is good for raising the price short term, in the long term it is going to cause Bitcoin to lose some appeal and actual practical functionality if we are left with an ever diminishing pile of available coins.
