I will try to explain ramp in a simple sentences " if ramp was a crap project and then binance will never listed it on its exchange site"
This time ramp already listed on binance and then you can draw your conclusion about ramp.
As far as i know that binance is always doing very strict audit to the any potential coin to be listed on its exchange site.
Exactly, very simple explanation. but I will only strengthen, that there is a fundamental difference between the crypto that Binance carries and the crypto that wants to enter Binance.
First, the crypto that Binance carries is a crypto that has succeeded in gaining a lot of popularity, one of which is a very fast ICO program in a short time, attracting large investors. That is the potential that Binance will target crypto.
Then secondly, crypto who want to enter Binance will be charged a fee by paying Bitcoin which is not small, because they volunteered, not carried by Binance, while those that are carried by Binance to pay will not be as expensive as the crypto that submitted the proposal, because they have quality. So the bottom line is good quality and growth rate, will be a target to enter Binance. one of them is like RAMP.
