I actually think the opposite approach might be the most optimal one, at least from a monetary perspective. That is, be on the cutting-edge of something, but be willing to bail out at the moment its future starts seeming questionable. Or even more specifically, maximize your foothold in it while minimizing your downside. Bitcoin is a good example: if you bought it 15 years ago and held it, you're probably quite wealt…
What would have you done when the Bitcoin fork happened 50/50? Would you have gone int ICOs? Which ones? Etc…
There’s simply too many “new things”, so by trying to get exposure to them you’ll be massively in the red.
Let’s say you get into 1000 “new things”, and you strike it lucky and hit BTC. You’d had to buy BTC in early 2013, hold it over the whole period and sold at the historical maximum for you to be at break even.
If instead of buying 1000 “new things”, you’ve put your money into the S&P you’d be at +250% by the same time.
