This has been helpful. Thank you.
Never heard of Sumokoin until now, sounds promising. Didn't know Charlie Shrem was on here, this is great. I came across him when I looked into Viberate , where he is also involved and I am currently researching.

Have you considered looking into Byteball ? It's a DAG based crypto and it has both transparent as well as private coins with regular GBytes and untraceable Blackbytes. I would like to see a review from you on Byteball.
