Decentralized exchanges are the future. It is not a matter of if, just when. And we get closer everyday, especially when you have governments that use fear as a weapon. The old tried and true top-down approach of most governments.
But there are a lot of platforms and inventions that are born before their time and without good marketing and incentives - these things can fall flat on their face.
Take me for example, I'm fairly new to cryptocurrency. I've only been doing this since April, and I've heard about BitShares and their project, but I didn't realize they had a working platform. I assumed (wrongly) that no one had a decentralized exchange yet. I have feeling I'm not the only one that thought this, which is why an effective marketing campaign is important.
Incentives can go a long ways too - like binance for example, who has the bnb coin which can save you money. The question that bitshares should ask is what does bitshares offer that others don't. I get that they offer a decentralized exchange, which by itself is big, but to be truly successful that line questioning can't stop there. There are only two things that typically drive traffic or make people want something. Either it's so attractive (in terms of what it does, offers, usability, etc.) that people naturally flock to it or fear.
