...and in 2018, 2nd richest man "Warren Buffet" said "bitcoin will end up badly"

May be in the next five years from now Warren Buffet will find it necessary to take back his word on that.
On the Bitcoin journey so far, I think we are gradually getting there. I am of the opinion that good things don't come cheap. Come to even think of it, the Bitcoin idea will take away financial power from the government and place it in the hands of people we don't expect government to speedily do anything positive to aid its adoption.
This just proves that bitcoin has been decentralized for 12 years. This is a good trend for crypto.
Yes, 12 years and still counting. Cryptocurrency in a budding industry that has come to stay. Greater things ahead.
