Show a button for sending quick donations to maintainers of bots, groups or channels using cryptocurrency. This could use either an established cryptocurrency like Bitcoin, Etherium, EOS, etc. – or some version of TON.
Cryptos with no or small transaction fees are the best for this feature
Salvador has accepted BTC. If the country can afford such adoption, Telegram must do it!
Looks like a fantastic idea to me, can't wait to see it!
I would suggest any type of donation, not just cryptocurrency. I would also like to donate to Telegram owners.
I like your idea.
The donation button would also be useful as a payment method for products sold through bot stores, I would suggest more commercial features added to the bot api, Telegram should charge its interest though which is also a good point
A very good implementation would be payment processing with cryptocurrencies. The conditions are available and everyone can have direct access to blockchains, so, Telegram servers can have a dedicated server that connect to every major blockchain in order to continuously check the transactions. The client send the transaction and Telegram servers informs when the transaction was made with the required amount, then continue the flow of the selling or inform the reception of the donation, etc. Another way is Telegram to create a wallet system.
