Amazing how many once hot & high potential crypto experiments failed.

Just a few on my list:

- Fractional NFTs / ERC-404

- NFT lending

- Music NFTs

- Elastic supply tokens/stablecoins (although $AMPL still alive)

- $YFI style 'fair launches'

- (3,3)

- Move-to-Earn (and similar Earn slogans)

- Two-token model (Bera might be last to try it)

- Algo-stablecoins (UST but sUSD depegged despite 750% col. ratio)

- "Stable asset" controlled by interest rates, not pegged to fiat: $RAI

- Stables backed by Protocol controlled value (PCV) like $FEI. 
(Olimpus DAO keeps similar Protocol Owned Liquidity (POL) idea alive.)

Failure is part of innovation. And crypto is amazing as we experiment a lot.

Perhaps those ideas were ahead of their time, like YouTube was before adequate internet speeds.

Sweatcoin has done pretty well in the move-to-earn category. 192 million users, or so its website says. 

Can also add bridged carbon credits to the list. 

I'm genuinely surprised fractional NFTs didn't take off, but I guess the launch coincided with the bear market.

Sweatcoin? Haha, didn't we all. That they somehow managed to scale despite crashing token prices should be studied by anthropologists.
