I've witnessed tons of PnD on Uniswap. So many BS tokens is listed there, so it requires very very little volume to pump a coin into the stratosphere and back.

Been trading at Blocknet's DEX for awhile, and really enjoy the fact that I can trade BTC LTC BLOCK and other coins. It's not built on Ethereum, which has it's advantages.
Their DEX is getting integrating into their multi currency wallet, which is getting released real soon (within a month or so). Here's how it's gonna look like: https://xlitewallet.com/

You don't see hard assets like Litecoin, Dash, etc moon on these DEX's, shitcoins does.. But that's pretty normal on traditional centralized exchanges as well.
