You blame the shallow orderbooks, but how many orderbooks of significance has come up recently? I can tell you, basically none. The total majority of bitcoins (if we talk about Bitcoin) are still traded at the top 3-4 exchanges (like Bitfinex, Bithumb, Bittrex and maybe a few others). So it is not about orderbooks as such, it is more about price itself. I've been telling that for years already, i.e. when the price rises high enough (and we seem to be there already), the supply will necessarily run dry. This is sort of a given. But when the supply runs dry, anyone can change it and thus dramatically affect the prices. This is the real cause of runaway volatility
This market lacks liquidity, and that by a huge margin. If the orderbooks were properly filled with legit fiat buy orders, and not orders from pussy bots pulling back everything with the slightest downwards movement, we wouldn't experience current level of volatility. Throughout the years nothing has changed in terms of orderbook liquidity, and that's something that definitely needs to change. At least, back in the days you could dump 100BTC into a $40,000 buy order, where nowadays this same buy order only manages to catch up 10BTC.
The higher the price is moving up, the worse this situation will get. That's why a global orderbook is pretty much the best possible solution to tackle this 'problem'. I find it weird that you don't see the importance of how much of an important role orderbooks fill in terms of volatility...
But you don't want to see the real causes of that
You blame the empty orderbooks, but it is like shooting the messenger. Even if you combine all orderbooks into a single huge orderbook, this won't help much in the long run (provided the price continues to rise, of course). With the price rising higher, this global orderbook will necessarily run dry as well in the end. There is simply no other outcome given that the number of coins is more or less fixed (i.e. monetary supply doesn't grow much). Indeed, new coins are still being mined, but they no longer make particular difference and now directly contribute to greater volatility (instead of preventing it). This is what I call a Big Rip theory of Bitcoin and now you seem to implicitly accept it
