That is a gem of an idea. I might just enter a writing contest on Steemit, using the rhino horn blockchain for inspiration. You couldn't make this stuff up. The Rialto coin, hmm, sounds logical. There might be something in that. There is so much innovation and creativity pouring into the space that it would pay to be involved in a collective, pooling one's thoughts - we do it virtually here, but I mean, physically, in real time, to maximise potential - vote for actions, as a group - have an investment pot and, to paraphrase Novogratz, the Ethereum tycoon, "ride this horse". That was absolutely fascinating about PBC - the rhino horn coin. Thankyou for sharing it here.
