I think of course you can still get 1000x returns. There will be ICOs in the future for all sorts of stuff which we can't even imagine yet. There will be securities tokens in the future which might be profitable companies and even the next Berkshire Hathaway. We simply cannot predict what opportunities can exist or will exist.

As far as the total value of crypto? We also cannot predict that in the long term. So when you say $10 trillion are you referring to by 2020 or some specific date? Because crypto could end up being worth 100 trillion over 20 years as tokens can represent anything stocks can represent and really any asset.

So I avoid trying to make these sorts of predictions. If we are talking about returns in Bitcoin then I can totally understand. Bitcoin probably can't go up 1000x because it already went up. Ethereum on the other hand can still go up 100x from the price it is today and within months at that. So I would agree that Ethereum can't go up another 1000x but then there are other tokens which can.

Especially weird for Vitalik to make that statement right now when this is the best time to buy crypto at these prices. He would have been more correct if he said it back in December during the bubble. Now in a bear market where you can get certain projects for pennies then actually yes we are back in the days where you can catch an ICO or even an established project at 40cents.
