Other hand  Michael Saylor, an early Bitcoin investor and proponent has  been credited with  institutional Bitcoin boom in December 2020. He has made billions of dollars from Bitcoin.
There are others like Mr Buffett and Mr Michael all over the world.

Truth be told  both investors are doing very well.  My question now is , Who is Happier?  Is it the Stock investor or the Bitcoin investor?

Then the dealer inhaled a large amount of money, causing the price to rise to a certain level and then clear it, and then retail investors will be injured. While it brings profits to investors, it also has risks.
Recently, the popularity of multiple cryptocurrency markets has continued to increase, and many traditional investment users have also begun to pay attention to the cryptocurrency market. How long can this trend last? Will it always exist?

Also people won't like to share keys with siblings or wife because they can misuse them . So what could be the solution to this
