To add: One of the problems is that some are 'heavy' in certain packs so maybe people only sell the light ones but dont say theyre light? But maybe that's a bad way to determine whether they have holos.
Trendy assets with no intrinsic value (e.g. trading cards, NFTs) are high-risk.
Assets like land and housing have utility. Assets like stock are supposed to have value because you have a share of the profits, although many people still speculate on public markets.
Put your money into something you use first, like a home purchase. Even if the price collapses, you may still be saving yourself money every month vs. renting.
Then move to something that generates value, like a high-yield index fund.
