although one can attest to the fact crypto isn't ponzi
I disagree, there're many ponzi scheme on altcoins this one example
Mere HOLDing isn't the best for bitcoin and other crypto with high volatility. Just like bitcoin which is never stable always having a fluctuation in price so much of experience and knowledge is needed crypto is just too risky
Disagree again, Holding is the best for Bitcoin more over if you combine Holding and DCA. You may not earn too much or loss too much, but at least it will minimize the fluctuation price. If you don't like fluctuation... I think Bitcoin, altcoins, forex, etc isn't your friends.
I'd prefer to hold Bitcoin over fiat because every months fiat value always inflated.
