Fedimints don't have tokens ecash is not a token, it's not another blockchain it's more like a redeemable voucher that gives you sats. So there is no token, there is a redeemable note, that you can use offchain and send to anyone via message if you want. Liquid has its own token that works like any other blockchain token, you pay fees etc. then you can swap back to bitcoin. Yes if the Fedi goes out your cash is probably gone, with liquid maybe the biggest risk might be one day regulators may order freezing the peg outs or enforce KYC to Fedi it's the same but anyone can run one so it's harder to regulate. Fedi and ecash you are always working with bitcoin lightning, you don't need swaps. So Fedi it's a better user experience. Fedi also offers more things, they hold bitcoin onchain, you got lightning, a lightning address, ecash and I think nostr integration, this are the best advantages. It's a whole package that integrates seemless with bitcoin.
