As you may have noticed, due to the fact that there are lot of bugs going on and my lack of time to fix them, the bot is going to be turned off. It may come back later, but I can't say when (I'd rather improve OBW and Cliche first). If it comes back it will probably have a different architecture.
In the meantime, please remove your funds using the /paynow command (and be patient as the bot funds bucket must be refilled manually by me as people withdraw, for everybody to withdraw the process will probably take many weeks).
If you want another bot for tipping people on Telegram, I recommend @zebedeebot (also on Discord), which I had a big part in writing therefore it can't be anything else than amazing (and I'm sure it doesn't have any of the bugs lntxbot currently has).
@zebedeebot works as an interface to your https://zbd.gg/ wallet, so you need to have an account there and to "pair" it with the bot once. You can however tip anyone without them having to have an account first.
