That's a little ridiculous thinking. So you suggest to not spend Bitcoin until it becomes trusted enough. If no one uses Bitcoin, how do you want the ecosystem to develop? The dollar is based on trust, the day people no longer trust, USD will become the new Zimbabwe dollar, yes it's a fact but
if Bitcoin needs to earn people's trust, it can't just happen without doing anything.
I believe this is not a ridiculous thinking. You must observe to all main bitcoin use cases. People in Venezuela use Bitcoin because their currency is completely devastated. So pepple believe in gold or bitcoin. You can see the same behavior in Zimbabwe too.
From an
investor's perspective, you're correct. It makes sense to simply hoard BTC until its value skyrockets in line with its stock-to-flow ratio.
The thing is, Bitcoin users aren't
just investors. Some of us also use it as a medium of exchange or way to transfer value, for various reasons: because it's cool and we're geeks, because it can be cheaper/faster than legacy means, to avoid taxes, censorship resistance for the dark web, gambling, capital flight, etc.
Hoarders are really lucky that other people are spending their BTC. If no one was transacting at all, BTC would have no value.
