This is actually a pretty great addition.
I've always been skeptical about the telegram wallet, but with new applications I now think it wasn't meant to primarily serve as a storage wallet but to make transactions easier and faster in an expanding network which is telegram. 10/10 addition.
The deployment brings more convenience to users but all users must bear in mind and keep practice with basic principles on security of their devices. I'd like to avoid installations or use my phones for too many activities and interactions with many platforms. Because by doing this, I know that I self-increase risk of security and more threats will find me.
The platform builds products, provide services to us but we as users, must know what activities we should do, and on what devices. Like if you use a smart phone only for entertainment, and not for your main fund storage, it's fine to go around with games and applications, widgets.
