They grow the volume of particular coin heavily and when it comes to the Binance like exchanger then it is best of all time. I have seen and observed that whenever the coin gets listed over the binance then it hikes by 20-40% or more in single day and this is because binance has huge user base and it is pushing the market to higher levels very quick as many people go and invest into it in very short period of time. This is what coins benefit is when it gets listed over the exchanger. It actually gains more investors as compared to the ICO period and thus make it bold, and liquid project.
