I certainly would not use the statement "Binance and PrimeXBT are two of the leading crypto trading platforms", when you use that statement you're implying that Binance biggest competitor is PrimeXBT while it's not true at all, if you want to promote your exchange it's better to be realistic and avoid spreading information that are not true.

Kucoin and maybe Coinbase could be considered as Binance closest competitors in crypto exchanges, in addition to that PrimeXBT is sort of a all-in-one exchange that includes cryptocurrencies, Forex and commodities in one trading platform while Binance is for crypto only, I've used PrimeXBT before and it was a good exchange over all but it's important to get the facts straight if you want to make a thread/post and promote your business.
