Unless you have an expert like Sigmike to develop and maintain the blockchain, then it's not a good idea to start your own chain. In fact even if you did it's not a good idea, as it's the old way of thinking that every single new idea needs its own chain, which is false.
It would be a better idea to build B&C on Peercoin using the new PeerAssets protocol, as the Peercoin chain already has a number of developers (including Sigmike) maintaining and updating it, as well as a larger community. Indicium is following this path, which recently raised $250k and is in development as we speak.
There is little point continuing to waste significant amounts of money on blockchain maintenance and upkeep when the money can instead be put to use on the actual business. Security concerns should be the problem of the host chain developers, not B&C shareholders. The owners of the DAC should remain focused only on the business. PeerAssets can allow that.
Not to mention BKS could easily be listed on any exchange Peercoin is already traded at.
