Are you saying that those bitcoins 'on the move' are going to be sold and the price will crash so hard that there's not much choice but for people to buy in, thus triggering the next bullrun?
I hope it's happening but, perhaps we'll be missing a year:

I was curious to fact-check that so I merged the graphs of BTC/USD and the one in your link (both scaled to 1 year to keep the same proportions):

To me, it just looks like the buy proportion is high when BTC/USD is at the top (because of FOMO) and low when it is at the bottom (because of panic sales). So exactly the inverse of what it should be...
