The volume in the last 24 hours is 10% of the market cap.. Nothings changed - people are just paying more for a $1 smart contract - I guess you would call it"trading at a premium". Look at the graph below for a 3 month view - the price is green the price of bitcoin is orange - you can see a relationship between the two.. the SBD got bought up probably because everyone is using the same trading software (and not doing their due dilligence) ;)
