SimpleX is an encrypted messaging platform like signal, threema, session, telegram, etc.
I'm surprised, a fair portion of both Bitcoin, and Monero people are on SimpleX.

Until all The BTC people will try to move to Bitchat, which don't get me wrong is also good but I'd prefer cross compatibility between both, or the features of one being built on top of the other one.
