So if you're a crypto investor and you died today, who reaps your fortune?
And since there’s no oversight from a court or a bank, it's irreparable!

Out of curiosity I dug into how NFT's actually reference the media you're "buying" and my eyebrows are now orbiting the moon
Short version:
The NFT token you bought either points to a URL on the internet, or an IPFS hash. In most circumstances it references an IPFS gateway on the internet run by the startup you bought the NFT from.
Oh, and that URL is not the media. That URL is a JSON metadata file
Here's an example. This artwork is by Beeple and sold via Nifty:
https://t.co/TlJKH8kAew
The NFT token is for this JSON file hosted directly on Nifty's servers:
https://t.co/GQUaCnObvX
THAT file refers to the actual media you just "bought". Which in this case is hosted via a @cloudinary CDN, served by Nifty's servers again.
So if Nifty goes bust, your token is now worthless. It refers to nothing. This can't be changed.
"But you said some use IPFS!"
Let's look at the $65m Beeple, sold by Christies. Fancy.

That NFT token refers directly to an IPFS hash (https://t.co/QUdtdgtssH). We can take that IPFS hash and fetch the JSON metadata using a public gateway:

1/ ERC-20 token standard approve() has caused an unnecessary cost of $53.8M for #Ethereum and #DeFi users
This is bad. Continue reading why and how to avoid this in the future.
👇👇👇
2/ Before you go all rage on the flaws of my analysis, please read the whole Twitter thread for disclaimers and caveats.
3/ approve() is an unnecessary step of ERC-20 tokens when they interact with smart contracts.
You know this because when you do a Uniswap trade you need press two transaction buttons instead of one.
4/ Why there is approve() - you can read the history in this Twitter
5/ I queried all approve() transactions on Google BigQuery public dataset and calculated their ETH cost and then converted this to the USD with the current ETH price.

1/ I just spend my Saturday morning on a call with a crypto fund explaining to them how #Ethereum ERC-20 token approve() function works
