I use different exchangers depending on the availability of the coin I want to trade and the price where it is worthy to be trade. But most of the time, I also use Binance because their design is simple yet elegant which I find easy to use and also they don't force anyone to pass the KYC first before Trading, that's the main reason why I like them. Their customer service as well is superb, in my opinion.
That is how it should be but people do not really realize that they should focus on the coin/token but instead focus on the exchange itself which is wrong if you ask me.
I understand the logic, sure if you like binance (which I really do, they are the best) you could use everything they have and by all means most of your deals will be on binance, anything major like bitcoin, ethereum or anything else they have on their list you can use on binance, but let's say there is this xyz coin that is not on binance, that means you could very well switch to that exchange and start trading on that exchange for THAT coin only, still go ahead and use binance if you want to with the ones binance offers, but for that specific coin you could have another exchange, and another coin with another, by the end you could have like 5 exchanges, 1 binance for everything they have and 4 others for 4-5 coins binance doesn't have.
