Keep in mind that gold skyrocketted following the US eliminating the gold standard. It was illegal for Americans to own gold from 1933 to 1975.
Gold has performed much better than holding dollars or other fiat currencies since 1980. Bitcoin will continue its outperformance by increases in demand.
Only a sliver of wealth has gone into Bitcoin and it's price will explode when people realize holding fiat in savings is a losing proposition.
You are correct that past performance doesn't guarantee future results. However, there is a popular addage: "history doesn't always repeat, but it often rhymes." Well, Bitcoin has had a few rhyming moments in its short existence.
I believe my assumption about Bitcoin is correct and am investing accordingly. Remember, Bitcoin/crypto is a new asset class. It offers several advantages over other asset classes and, admittedly, has some drawbacks as well. At the end of the day, Bitcoin is scarce and sought after. Houses are scarce and sought after.
