Sure the concept will be copied, but where?

Are you going to open up a de-centralized exchange on ethereum? Someone could do that yet they might have an issue with the transactions.

Someone could start a new blockchain from scratch, which might happen...but they are already falling behind.

And BTS doesnt need to own the decentralized world to be highly valued...there will be other exchanges....but who knows what else BTS will add to the mix over the next year or two.

The developers are still hard at work on that blockchain just like on this one.
