Why not switch from Whatsapp to Telegram?
- Messaging is strictly encrypted
- Message delivery is super fast
- Larger groups: 200 members [this CAN be useful!]
- You can build stuff using their API [CE-Messenger, Anyone?]
- They've got dedicated desktop apps for Windows, OSX and Linux
- They've got timed messages - if you need those.
- Allows you to store media on the cloud - so it can be retrieved later on
