It is quite interesting, and I use telegram with a crypto wallet that I have activated.
But the crypto wallet generated on telegram cannot be exported to another crypto wallet and you will also not get a seed phrase.
That means we as wallet owners do not have full access to the wallet and only Telegram knows.
I don't really use it for my main assets, just use it to explore TONS of space and the ecosystem within it with the minimum funds I send to my telegram wallet
