I think I'm also in line with what you're saying here.
I don't think Warren Buffet knows a lot about cryptocurrencies because he hasn't really studied them. I say this because I currently work in the financial services industry (closing in on 13 years now). I know a lot about stocks, bonds, and the markets in general. Even so, I recently told my wife that me learning crypto is like a horse-and-buddy driver looking at a new Ford Model T. Some principles carry over. Others don't. It took me about 6 months of study before I even got myself to the point where I could invest a decent amount into any cryptocurrency!
However, I think -- as you said -- there will be a "shake up" in the industry just as there was a "shake up" in the financial markets during the Tech Bubble burst and the Subprime mortgage meltdown. There are a lot of coins out there that are out there because it's cool to have coins; I've already bypassed several ICOs because there isn't a uniqueness (or reason for use) and I'm putting more into some of the larger coin.
Ironically, I have begun to share my experiences -- especially during 2008 - 2009 -- with those in my Facebook groups. In my opinion, the most dangerous thing to an investor -- stock, mutual fund, forex, or cryptocurrency -- is emotion. Emotion will take a normal, everyday person and cause him to put in more than he can afford to lose or make a knee-jerk reaction and pull out -- at the worst possible moment -- during cases of extreme volatility.
From what I've learned, the cryptocurrency space is far more volatile than where I am in the mutual fund space. Hence, it will be even more important for people to plan, stick to those plans, and not let positive - or negative -- emotion cause them to make knee-jerk reactions.
