Dot Com had many different ideas. This bubble is more dangerous as it's very centric on the same ideas. Also, it's highly leveraged and liquid. During dot com you couldn't float an idea and get 300 must in two days without even a plan. Any new gen coin with early success sparks 40 more. The collapse will be gigantic here, but maybe 2-3 platforms will become behemoths with a 400b+ market cap. But just a few, just like there Google for search, Facebook for social, etc. there can be many coins but 90% will be the top 1-4 coins and smart contract leaders.
Absolutly, there WILL be some new Googles and FBs from this season tech I have no doubt. But also the old establishment like Google of they see success will build their own as well, imagine Google doing an ICO? INSANE!!!! Amounts of money would be collected.
My strategy is to wait until the dust clears most will drop to worthless and then we might slowley start to see who might be the winners. I would say Judging that now is almost impossible.
