If you are like me you can even use Telegram.

For the things I post on Telegram I don't care about crypto but rather about a good desktop client, features months ahead of Whatsapp, nice niche communities, bots (including the hn bot which is really nice to see all things that have been voted above a configurable threshold during the day.)

Now that I think of it a lot of what I use it for is as a RSS and twitter replacement: subscribing to channels and groups, occasionally posting harmless stuff.
