Thanks for this - always good to hear other people's views! I went to a Chainium event yesterday in Bristol (debrief here: https://steemit.com/blockchain/@felicitee/blockchain-startup-chainium-token-sale-in-march-to-disrupt-usd76trn-equity-market).
Certainly a smart and experienced team, with a good atmosphere in the room. The team is currently pretty small (5-6 people), but hiring - and has no lack of ambition!
