Welcome, it works like a charm^^

thanks! I still don't understand what locking bitcoins does or what its general purpose is tho

you are not derp alone. find derp aswers in this thread: https://home.treechat.ai/quest/6a96f2d4-4160-493c-bdec-0d9641e7c155

if you share your bitcoin receive address i can send you some sats to try locking on messages you like. you can find it by clicking on your avatar top right of the screen, and then clicking wallet
