Good to know. I don't know exactly what caused the problems for Bottlepay, but they started as a simple LN tipping bot and had to shut down because of such regulations. And could only come back (with a slightly different product) after clarifying their legal status. They have a telegram group (https://t.me/bottlepay) where you can find the contact information of its owner (Pete). Up to you to see what's the best strategy (see how it goes or proactively comply). I'd also like to believe in a world where decentralized and non-custodial mean what they mean, but until we get there...
