Well it is a good one but I believe it would be best if the owners of whatsapp implement crypto directly into it's platform without someone developing a bot because it is a norm for me and I see nothing too big in it if someone created a wallet for whatsapp, it has been very rampant in telegram and just newly introduced to whatsapp, let's just keep watching and hope for the best in this our great community because the best of us is still yet to seen.
