Each crypto currency (well most) act like a collectors marked, i.e like art, antiques, trading cards and so on.
The only lottery aspect is weather or not niche currencies become well established, kinda like weather or new sources of classical collectibles become well established.
Some now would argue that collectibles in difference to crypto currencies have a real world value which backs them but that's a misconception such real world value is most times completely negligible if the collectors marked fails. In some cases it will even cost you money to get right of the now basically worthless collectibles.
Also similar to there being cryptocurrency which are a scam there are collectibles which are such. Like supposedly priceless pictures being sold for over a thousand dollar being only worth like 5 dollar or so, i.e. you basically lose the full investment
