I think Fedimint is an awesome project and a game changer for bitcoin.
It will allow anyone to get access to a lightning wallet with 0 friction but still provide a custody setup that is much better than any custodian lightning wallets that exists today.
At the same time, it provides amazing privacy for it users which is better than any other privacy options we have in Bitcoin today.
I also like how it sort of pushes all of the lightning node functionality to another layer so that the federation members themselves do not have to worry about maintaining a lightning node.
I am also interested in possible Fedimint modules that can be built. The obvious one I see is a federation scoped asset exchange. Basically allow users to mint assets for a fee and trade the asset among members of the federation. These assets could represent shares in a company or anything and could also have really good privacy.
A possible hurdle I see to Fedimint's adoption is regulatory capture of the federation.
I would love to hear some other opinions!
