maybe it's a binance way to avoid scam projects, of course binance will maintain its image as an exchange to avoid fraudulent projects, if your token is registered in binance, of course people will not doubt your project, for the cost of the token list in my opinion is too excessive,
It looks like you are serious about your project, good luck.
Indeed, Binance is trusted on this matter of assuring scam projects to be prevented. If ever they've been breached with some circumstantial situations through security and it happened losing their traders funds, Binance will took over for the responsibilities. Hopefully, the other exchanges like Kucoin, OKEx, Hitbtc, Huobi and Bittrex would have this kind of core strength in handling over their client, because as we all know they've been doing trading smoothly without any huge issues concerning funds lost. Because of that capabilities, all traders and holders hope that their coins will be listed in any of these exchanges for the expectations that it could reached the most potential profitable value.
