What are your favorite crypto use cases for regular people?

Outside of speculation and DeFi speculation, what are your favorite use cases for crypto that regular people can easily participate in?

Two that come to mind for me are the Reddit avatar program and the recently announced Kare Survivor Wallet.

I like the Reddit NFT program because anybody with a credit card and a Reddit account can easily participate. It’s still probably too complicated for many people to sell on the secondary but once reddit creates a marketplace this will be seamless.

I like the Kare Survivor Wallet because it streamlines the process for receiving funds in a disaster and will also likely cut down on fraud due to the transparency of transactions.
