Haven’t heard about this thing and for sure very limited you can do on telegram bot, it can’t be trusted as well. If we are going to push for a crypto banking then it must be the best and secured, I cannot trust a cryptobanks that works like a normal bank, telegram is a great community but I don’t think banking system will work on this.
why so?
telegram runs great secured service, as far as I know
And it spreads among all countries with confidence each year.
So I don't see why banks should lose such opportunity
