What people dont understand is Bitcoin was intentionally designed to NOT be scalable. Scalability is the most fundamental design criteria whenever any software is designed for the masses. The reason given to the average Joe is that the miners don't want it to scale because doing so will reduce their profits. The real reason why there is an opposition to scaling solutions for Bitcoins is simple - the memory pool is being used by the big boys for inside trading.
In the very long run, there will only be two dominant crypto-currencies. Which two? time will tell. But why two? whenever choices are presented to the people in any facet of society, from carbonated drinks to political parties, there are always two dominant ones and possibly many other alternatives.
The next few weeks cyryptos will take a bloody beating, panic selling, lower lows and the crypto market will indeed recover, but the wounds will be so traumatic. The trauma will lead to more 'gittery' future investors, ones who have little trust i.e this coming crash will create the weakest hands the crypto world has yet to see. I believe cryptos will recover after the crash, but the recovery will be slow.
Just know that if you panic sell in hopes to get in at a cheaper price, yes you may get ahead, but you are ultimately slowing down your long-term objectives since your panic sell contributes to the price dips and ultimately to the negative volatility perception, this in turn will make future investors(who you rely on) more skeptical to jump on the crypto space.
You can think greedy (and self destructive) by selling your cryptos or you can do the community and (yourself in the long-run) a favor and hold your crypto As we say, "HODL" (HORD+HOLD)!
