If you have $1000 some years back, you used it to buy bitcoin, the coin now is worth $10000 BTC today. When you needed $1000 and you converted some to fiat, you still have $9700 BTC left, not $9000 BTC. This has been what I noticed if comparing my country's local currency with bitcoin.
Bitcoin has value because of fiat which is used by government to scam ignorant citizens to let people know that they should not hold fiat but get a better asset like bitcoin, gold, silver...
Aside from the fact that it's something I really like, what does Buffett think ? The only thing I see him wrong about is Bitcoin, because he's an intelligent person with excellent books.
He is 94 years old
, age can make someone not follow new technologies.
He was very wrong.
