I'm equally worried - I do believe the BTC is very much overpriced now, people are buying because the price is increasing and the price is increasing because people are buying. Most of the new investors have no clue about such things as the capacity limit. They are either just buying on the FOMO, or they are buying on the promise that Bitcoin may become the dominant payment rails of the future. I fear that Bitcoin will crash hard as soon as the mainstream media picks up how bad Bitcoin really works. Quite some Bitcoin Cash fanatics hope for this "flippening" moment when the Bitcoin value crashes completely and some other crypto takes its position ... but no, I believe you are quite right that this will hurt a lot for the whole crypto community and not only BTC.

Luckily there seems to be quite many potential bag holders that will hodl to their precious bitcoins no matter what :-)
