Yeah, that's a question I keep asking myself these days. There's so many DEX projects, some of them not even being "Real DEX's" like the Binance "DEX". I've been wondering if another bull run could trigger a huge influx of new users towards these projects, since you don't need to own an account to use them.
Remember Q4 of 2017, when you couldn't even open a Binance account since they got too many registrations at once? With the recent influx of new trading options, some of the volume could be moved towards decentralized solutions such as
Blocknet, just to name a project.
Another thing worth speculating on, is people seem to HATE KYC like the plague. Imagine all the rich and wealthy people, like celebs, and people with big time careers, they might not even want to risk disclosing what they hold should a centralized exchange be compromised, which makes DEX's the best solution.
Could 2020 be the year of DEX's? Just a thought...
We may need more exchange hacks to convince people to start using Decentralized exchange platforms,but lot of people facing issues on DEX while doing trading that is why they are happy with paying the fee and getting their prompt service until they were trusted and making profits from those centralized trading platforms.
