The pull back may be filled in by the number of people rushing in.
Will it go higher? Much! If crypto-currencies are going to be the new money, then we have to get close to 90% of the people into them.
Going from 1% to 90% is a lot.
But, maybe less that we think. As most of the "money" is tied up in bubbles and assets created out of thin air. The derivatives market cannot get into cryptos. (all the smart contracts would have already triggered, and everything come crashing down) And so many people are living hand to mouth. They literally will get into cryptos when their boss starts paying in cryptos.
Agreed, if we don't get any substantial pullback before Christmas then these prices will never be seen again. The rush after Christmas will be real as people flood in cause the "weird uncle" is crushing it in BTC. ;-)
Taking it a step further, what is the easiest way for a brand new entrant into the crypto space to participate. It's BTC, LTC, ETH so these will most likely see the vast majority of new money coming in.
I think from that we start to see old money (in this case last 2-5 years worth) get out of ETH, BTC, LTC and move into promising alt projects.
Giving bitcoin for Christmas is a real thing. I don't see any pullback taking us below $12K ever and definitely not before new years.
