The premier Dex on Pulsechain when it launches. Uniswap and other dex's will be forked over but there will be many reasons to use PulseX instead.

That is most likely where most of the liquidity will go
There will be an additional incentive token for liquidity providers

But honestly, the biggest thing about PulseX will be the buy and burn function. A portion of the trading fees (which is 0.29% while uniswap is 0.3%) will go in a pool that has a public function to buy then send to a null address, thus, buy and burn.

Pulsechain isn't even out so you haven't missed out on anything. Plenty of time to do research I am not a financial advisor just letting you know you'll run into plenty of FUD so have fun lol
