The percentage growth in bull markets has actually not been slowing down. The 2017 bull market was actually 'bigger' percentage wise, compared to the 2013 bull market.
I do expect the markets to stabilize in the long run, though, and volatility wouldn't be as prominent as it is right now.
But overall volatility has definitely been slowing down. The market has gotten bigger and will get bigger. Obviously it was easier to buy even $100 worth of bitcoin and move the entire market back in 2010 or something like that, because of the fact that the entire market cap is simply so small. That's why you see prices move way faster a few years back than it does now.
True. I think the point is that i am confusing rate of supply of bitcoin with selling the bitcoin. Before a bitcoin is sold, it has to be created, and that does not diminish its value… So the point is about market cap that was very low at the beginning. It all makes sense now.
I have another idea, which maybe is a bit off-topic. Let me explain:
If the ratio of total bitcoin value of usual holders per total bitcoin value of criminal holders gets too high. There is, in my head, the possibility that bitcoin can start to really fall in value after some boom (that occurs from 2 to 2 years +/-). The idea would be that usual people, including, i don't know, JP Morgan desks or whatever and other actors, (institutions' behaviour are the big unknown here), after a boom, would start to sell their bitcoin positions like crazy just to hedge/short (to buy them only when they are very cheap), and this effect would be stronger than what is to me the great hodler of all, the criminal person, that does not want to short and prefers to stay more quiet and hold in bitcoin everytime.
I mean, i know this is very anti-market ideas but in financial markets, things can get messed up very quickly if the market is irrational as a whole, which is happens, even if many people do not want to admit. So the idea is that, at some point, that ratio would be so high, that, it would be possible that bitcoin could reverse the long term trend. (yeah, i know, HUGE hypothesis) Anyway, in extreme, the price would get back to the earlier level, and then the long term trend could change again (to positive growth), so, not so biiiig deal after all.
In the end, it is just a theoretical possibility. We have had great busts after the booms, but my point is that those busts can be a lot greater in the future, if more and more bitcoin holders start trying to short.
PS: I think we are experiencing the second major (in relative terms) bust since the beginning.
