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? If there is no ecosystem people won't get interested in and Bitcoin may become a currency like the currency for Second Life (the video game (?) with its currency, not sure if I'm right)
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.
Maybe that will happen, but those who did it literally are dumb people. It doesn't mean that don't spend now, you will not spend it in any necessary thing. That will really make you poor and ridiculous.
Too much spending is the wrong doing which is this thread is all about. So that's not my point, using bitcoin WISELY while waiting for it to rise again is a good strategy. Minimize your spending for your own necessities and not on your wants.
However, it will still help for the promotion of bitcoin and earning the trust of the people based on how you use it.
You cannot say that they are dumb people, there are people who using bitcoins in their daily lives and there are also people who holding their bitcoins. Those people who spending are the one who using the advantages and function of the bitcoin, maybe they using bitcoin for them to survive in their daily lives like what happened in Venezuela where their fiat money doesn't now have value anymore.
