For quite some time now, I'm having exactly the same conclusions on your adequate "euphoria and depression" model.
Steady and generally gradual growth, seems like the only way possible. Any other than that fills the market with doubts and uncertainty and those simply can not work well for businesses of individuals. Nevertheless this is free a market, one of the last truly free in fact so it will arrange itself without our help. Whatever its path will be, it's going to be a wonderful study and I found myself lucky to ba a part of it.
Steady and gradual will NEVER happen with crypto though it would be preferable in many ways.
What people tend to forget is that every other market they're familiar with has the value they start trading it at either decided by centuries of track record, like gold and silver, or some stock analyst who decides the price that trading begins at.
Crypto's come up from zero. No one knows where it's going to go. No one really knows what it's for. That's a guaranteed recipe for violent volatility and it's playing out exactly like that too. Birth is not a smooth process. It's a series of contractions. That's what's happening here too.
