Canis, your thinking is valid and you got a point. You are thinking out of the box, I like that.
However, I think you got it just a little bit wrong. Yes, if speculators want big profits it is indeed beneficial to them for the market to correct (this should be the right term, not "a crash", a crash means that the market went past the possibilities of a quick recovery and it never happened with Bitcoin, at least not so far). It is also normal to see the market rise in steps, the market just rising up is an ideal that cannot be reached in the real world (although Bitcoin's run from the end of the last year was crazy.
Well, opinions may vary but as far as my opinion is concerned, I think that a price fall as low as 30% of December highs pretty much counts as a crash. And we are still half the maximum price of $20k. We haven't seen a fall that massive since the Gox fiasco, so it is not something which can be called "normal" whatever yardstick you use. Anyway, right now it is definitely not about "market rising in steps".
What Bitcoin needs is for the weaker hands (Poker expression is deliberate) to leave the market thus leaving only the strong holders - albeit corrections this actually stabilizes the market. You can consider the market mature only when it stabilizes and that would mean that generally only strong holders are left and the 1-5% percent of weak holders and daily speculators cannot hurt/destabilize the market. The current situation when you have the market reacting to almost every news out there shows us that Bitcoin is far from maturity and that is the ideal situation for experienced investors to take opportunities and take all the money from the fish (Poker expression is deliberate yet again).
This is the interesting part of your post. Your main omission is that weaker and stronger hands are a relative notion. I remember I have already mentioned it somewhere and maybe even in this very thread. In a nutshell, there will always be strong and weak hands, there cannot be only strong hands in the market. It's kind of a given. While weak hands leave, less stronger hands remain, but it takes even higher volatility to shake them out. In other words, it works in the opposite direction toward more volatility. Obviously, this is applicable only to speculative markets, but Bitcoin undoubtedly belongs to this category.
