Thanks so much for this. These sorts of insights are invaluable for those of us newer to the crypto space.
To your point about "character", I saw Arthur interviewed on Bitcoin Uncensored. You can count on Derose to ask some tough questions (even if you aren't a fan of his style). Arthur's responses and general demeanor left something to be desired IMO. Maybe he's a great guy with good intentions, but reading people's facial expressions and tone can be helpful.
It's possible we as a crypto community are an overly skeptical bunch, but sometimes you just have to listen to your gut.
