If you only hold €50-100, then self custody lightning might not be worth the hassle or cost (assuming you're not completely against custody solutions). There's two competing #ecash protocols that seem to have a lot of promise: #cashu and #fedimint. Both are fully interoperable with lightning. On the cashu side, #minibits is an awesome wallet app that supports NWC. Works flawlessly with Amethyst. In theory cashu also has really good privacy. The mints use blind signatures.
