Do you have major partners? Or are you going to cooperate with big companies? It will be very difficult to compete with the TON(
We are targeting Multimessenger , TON will work on only 1 messenger but BITSUM will work in multiple messenger
But TON will be full in App accepted and User can send directly to User without knowing the Adress.
Furthermore the Bot solution is bad because Bot owner has also ALL PRIVATE KEYS from everyone which is using the bot.
This is a big risk and thats why I think that SUM is useless.
