They state in reference to bitcoin: “take advantage of the largest blockchain technical ecosystem"

As a person who is fairly familiar with bitcion and bitshares/steem capabilites I would be very interested to hear what - (other than blockchain hash rate ?) exactly they think the advantages of this "largest blockchain" has over the Steem block chain. As I see it, they are at a great disadvantage for many reasons, the first being the steem is custom made for the particular application...... very fast confirmations, no fees, flexible & responsive monetary policy... etc etc. Bitcoin can not match this.
