That is almost impossible... there are many other DEX out there, plus with Bitfinex building on top of EOS and Binance crating its own DEX nobody will care about BTS.
To me Bitshares looks abandoned and I was also kind of disappointed by Dan's comment about Steem (how he wants to build completely new social web page on top of EOS). Dan likes to build new stuff and he doesn't really cares too much about his previous projects.
I know Stan has plans to integrate BTS into EOS but I am not so sure BTS will benefit from it. Why do you want to run your exchange gateway on BTS when you can build your own exchange (using open source project code) on top of EOS ?
I personally invest mostly in EOS these days. It is going to be huge.
