It's hardly possible for such large projects as the coins you listed above to attain a 100x growth, let alone 1,000x. As we all know, this did occur in the past, however coins which were started before the ICO hype collected very small amounts of money in comparison which made such a multiplication possible. Nowadays, when a coin's market cap is usually in excess of 20 million USD, then a 100x growth would mean a market cap of 2 billion USD, which hardly any coin save for the few most prominent ones could achieve in the foreseeable future.
Crypto will definitely grow and many more coins will have 2 billion market caps. The next billion dollar coin definitely is out there already.
It is however also inevitable that many crypto projects will prove to be unsuccessful in the long run and will fail either due to competition, lack of skill on the part of the team, no demand for the product they're offering or whatever other reason. Once this starts occurring, I am rather certain that the cryptosphere will experience a severe price correction, after which the prices of the projects are likely to adapt to reality - basically, after the bubble bursts, there will indeed be survivors who might emerge stronger than ever and reach the billion dollar caps you suggest. But for the vast majority of projects, I don't think that a billion dollar valuation is reasonable or sustainable.
