+ NFTs (we know about one user who sold an NFT for $60k that he won for free - a life changing experience)
+ DeFi tokens (liquidity pools, staking, farming are all giving huge returns for small investors)
+ P2E (Play 2 Earn is another way to make money by playing games online and getting tokens or NFTs as rewards, some games have different types of rewards)
All but the last (unless that includes pay to play to earn) carry a substantial amount of risk with them.
Sure you might get lucky with an nft, but what if you don't? Your collectible nft may rely solely on the ethereum chain remaining stable for you to be able to use/possess it.
I've seen defi tokens to a bunch of different things. Sure sushi and uni were quite saught after and might not be much risk but some icos in that space have crashed kinda quickly.
Investing in innovation might come with more risk than people are willing to grit their teeth and bear for the payoff (which could, realistically be small if you've made a mistake or the team you've invested in have).
