WhatsApp vs. Telegram: Here’s Why We Recommend Telegram as a Better App
The biggest selling point of Telegram is security. Other than being an open-source platform, this messaging app also makes use of MTProto that features 256-bit symmetric encryptions, DH secure key exchange as well as RSA 2048 encryption. This is just how secure this application is, something that has even prompted the developers to offer a massive $200,000 for any hacker who can find a loophole in the system.
Based on the above revelations, the conclusion here seems obvious. Telegram is a no brainer, has great syncing capability, better security options and extremely fast. Even though WhatsApp is also simple and fairly fast, it lags behind in certain key aspects that have been highlighted by Telegram.
