The article is arguing that you aren't likely to be able to pick the ones that will grow faster than the economy as a whole over the time frame you intend, because it relies on an extreme amount of right-place-right-time luck. If you were looking for the next Beanie Baby for the last 20 years, do you think you would've found it? I think it's also arguing that the particular appreciation you need to capture largely on…
$1 on Bitcoin ten years ago are worth over ten million dollars now. And I think people thought Bitcoin had potential, even back then. Definitely something you wouldn’t mind spending a few bucks on. But back in the day it was quite different for average folks without enough tech knowledge to mine or buy crypto.

"Bitcoin's price rose again on April 13, 2011, from $1 to a peak of $29.60 by June 7, 2011, a gain of 2,960% within three months. A sharp recession in cryptocurrency markets followed, and Bitcoin's price bottomed out at $2.05 by mid-November.4 The following year, its price rose from $4.85 on May 9 to $13.50 by Aug. 15."
So let's use that $2.05 price as "ten years ago," I'm willing to give you 10 and a half years ;). A dollar in bitcoin then would be worth about $20,000 now.
So sure, pretty good. Nowhere near tens of millions, though.
And that $30->$2 change, and a few more up/down cycles between 2012 and 2017, shows that plenty of people thought it had already peaked. See also the various "oh no I lost my hard drive with the bitcoins I'd mined since I didn't think it was that important" stories. So sure, getting in for just a few bucks before 2011 and holding? Yeah, you're looking super great! But most people hadn't heard of it by then, and that's not who the article is talking about... when they did hear of it, you had a huge wave of pump-and-dump shitcoins proving the point of the article: the average person getting in at that point was largely too late for the level of return they were looking for.
