Another video from Crypto Coins on youtube. He makes ARDR seem, at minimum, like a great coin to follow. I wonder though what Ardor's main competitirs are. Sounds like it competing with Stratis and NEO. I could be wrong about that.
Anyway, he did the work. Check his youtube and steemit pages below.
