I do not know there are trading platform present on Telegram in a way people can do some task like spot, future and copy trading. Bit I can not house it because I have the app of the exchanges and I can easily click on the app to access them. I do not think anyone would have used the app or trading platform before and still want to use Telegram to access it.
There are a few bots and mini apps but they are not supposed to be the trading platforms just showpiece features for reputed platforms they won't get involved for this showpiece as well because it brings many security concerns as well and yeah if you are opening telegram app for trading why not to open an other trading app which is meant to be for trading only.
for me those things then do in telegram in the name of trading just like a ponzing scheme because threading is independent of it home from it platform especially all this age change not a telegram group that people can creat and tand add more people for them to be their accompanists of fraud
A couple of spelling errors must be optimized to give an efficient answer and for a healthy conversation. Your comment about what they are doing is absolutely accurate. Still, in my view from mini trading platforms, it refers to these new apps on Telegram that allow the swaps and transactions through bots and other layered mini-games like all this shit going on these days.
