The first step to wealth is saving a part of your income, which you should invest into business to makr money while you sleep.
How can people save today? Only gold and btc imo. And with recent bank failures, my conviction has only grown.

Broad spread investments. They might not do much, but they should protect from inflation. IMO US equities tend to be overpriced so maybe avoid that market.
But BTC COULD go to zero. We are at the "then they fight you" stage, and we haven't yet got widespread merchant adoption. It's only money if it can be turned into food. It is possible that Gvts could in effect break that step IF they decide to co-operate to do so. UNLIKELY (I'm long, remember), but certainly not non zero.
CASH is not, and never has been, a thing to hold long term. To an extent the BTC vs Cash thing is valid re "lightning for instant settlement", but a red herring if it's "buy BTC for long term value". The correct comparator there is maybe gold, but better still, a "low risk" basket.
