There are several ways to look at Bitcoin:
1) As a speculative investment. Buy low and sell high. Nobody really know which way it’s going. You’re gambling
2) As a way to optimize a given financial transaction. If you’re buying something illegal, looking to avoid taxes, and want to get around issues with an International transaction…bitcoin may be for you. Just don’t hold Bitcoin for too long, unless you also want to also speculate (#1)
3) Long Term improvement in how payments are done. How is Bitcoin better? Credit cards are better than Bitcoin because if you get ripped off, you let the credit card company take care of the problem. So how is Bitcoin better? It doesn’t make the transaction easier, there are plenty of financial tools with regular money. Is the transaction cheaper? PayPal and Venmo are free. So I don’t see any strong use cases here.
4) Long Term Management of monetary policy. We don’t trust governments much, but given SBF’s impact, this doesn’t sound too realistic.

Given the above, sounds to me like Bitcoin is good for criminals and people with money and power who want to avoid taxes and government oversight. Well, might also be good if there is a global collapse of economies and governments, including the US…but if that happens, some of us rather not be around for that.
