Well, to be fair, there's a hate thread for every exchange, even exchanges that only does trade with non-Shitcoins like Coinbase but then Bitcoin Cash is a shitcoin too, so really, the only exchanges that don't trade shitcoins deal only in Bitcoin haha.
But back to seriousness, if you want a decentralized exchange, then be prepared for everything including and especially shitcoins. A true dex means any coin can be traded, that's the whole point of a dex, freedom of choice, no control or decisions taken by any centralized parties.
Completely agree. It's a feature that either a good thing or a bad thing depending on how it was utilized. It is great in a way that there are no listing fees, no middleman, and everyone can basically trade any token (since most DEX nowadays is only for Ethereum Based Projects) to anybody; But, Sadly, most scam ICO's tend to promise on getting listed on DEX exchanges nowadays just to lure in investors. This type of scheme is what is tainting this great feature of decentralized exchanges.
