After
Tesla bought $1.5 billion worth of bitcoin, the price of bitcoin increased to over $50000 after some days,
Microstrategy bought $1 worth of bitcoin at the time with the price slightly above $50000. Although, Microstrategy has been buying bitcoin before, but saying big companies are not buying bitcoin after Tesla bought bitcoin is very wrong.
Grayscale also open investment for investors. That is another big company in the crypto community, Grayscale bitcoin holding has increase to over $38 billion recently.
There are many other institutions that have been investing in bitcoin, it is just a matter of time, more big companies will join and invest once the creteria before investing in bitcoin is fulfilled, this can be more increase in marketcap. Bitcoin is the digital gold, it will not be surprising to see bitcoin marketcap getting to 5 trillion in a decade to come, or before. What is most important is that bitcoin is deflationary, and this makes people becoming to prefer it than other assets also because it has limited supply of 21 million which makes it appreciative in design.
