amazing chart yes. but that took 30 years, people here get afraid when bitcoin lost 20 USD in one week

i think its an good investement but a risky one. either we lose 99% or the price will rise alot.
I can see other scenarios than Bitcoin becoming massive or disapearing
Owning berkshire means owning a slice of a huge conglomerate of profitable, growing businesses. Owning bitcoin means owning an electronic numerical value that's guaranteed by the network.
Berkshire is a productive asset, bitcoin is effectively an e-commodity. There is virtually no intrinsic value in bitcoin (it doesn't generate massive amounts of value for society). Owning berkshire for long periods of time is investing (long-term profit and value growth), while owning bitcoin for long periods of time is speculating (believing the next sucker will buy a non-productive asset at a higher price than you).
Bitcoin has massive intrinsic value. Eg replaces 1/2 of the world banking infrastructure for one.
Bitcoin obv has intrinsic value
I think OP made a very interesting parallel because people get anxious after a 2months decline or a 3months stability when long term means a longer time than Bitcoin's age and Bitcoin's future looks very bright
1991-1998 1000%, B.A doesn't pay any dividends, he choses his companies very well and paid a small price while leaving the good managers in place with a lot of freedom but removing the bad ones; look at his portfolio
