New wealth can only only be created from economic activity, if everyone only buys Bitcoin and no one starts companies, hires employees, improves equipment, discovers more efficient techniques, or consumes then overtime the economy shrinks, and the money becomes worthless as no currency circulates.
I'm not saying saving for emergencies, the future, or retirement are wrong but what I am saying is hoarding wealth just to never deploy it is worthless.
Bitcoin's value comes from its use as a currency that circulates due to Peer-to-Peer Trade, if Peer-to-Peer Trade isn't happening with Bitcoin then it has no value.
