It's not telegram who has integrated it, they aren't related so title is misleading. If it was telegram they would have tweeted about it and announced it themselves. telebit isn't user friendly, you have to add telebit to contacts and need to type commands to it to get actions done, also no airdrops, no advertisement model, no context aware smarticons, no multiple reward models, no in-build wallet.
Unfortunately, the text based user interface and the non-intuitive set of actions required on the telegram GUI to initiate btc transfers to other users makes it completely unsuitable for the normal (non-tec-savy) user.
what is needed is to have the BTC wallet built-in to the telegram GUI. unfortunately, this is unlikely to happen, since telebit is not affiliated with telegram.
I just took a look and it's more of a hassle to send btc, you need to click on the username you are chatting with to open profile, then click one of the options (probably share) and then you need to click on user telebit to open conversation with it and there you need to put in the amount you want to send. So you can't directly just send it with the person you are chatting with, you need to go through multiple steps, i mean wtf.
