I know that ArcBlock is blockchain 3.0 so I wonder that what price it can grown up. If ETH is 1200$ now, do you think Arcblock is more?
Im sure ArcBlock will be good for a long term HODL investment from the ground floor, but I want to let you know the Komodo Platform is about a year old, very well developed, and I think covers a lot of this territory.
