but i think his exchange services constitute more on the risk involved in cryptocurrency, while knowing this he could have maintain only dealing with bitcoin than altcoins which most have resulted into scam related offenses
Binance is an exchange, the exchange will try possible best to list good coins, but some coins can turn bad like Luna and UST.
i think CZ motive is just to make business and profit out of it
Definitely. If you have an organization, won't you want profit? All you will be looking for is to make profit in a legit way if you think you can.
I still see XRP, BCH and other shitcoins were listed on Binance, they're not removing the whole shitcoins yet.
It depends on what you call this type of coin, they have high marketcap and I can not call them shit coins. In coin listing, Binance is better than many other exchanges.
This is not new to anyone who's involved into crypto. Only a newbie will claim not to know the high risk of crypto. By the way, you can not blame CZ because the main purpose of business is to maximize profits at all costs thou it's not supposed to be detrimental to others. You are therefore required to do diligent research before you invest in any shitcoin.
You can say that again, you are not wrong. As CZ said it, it can help beginners, even if not helping, saying it does not take anything from anyone.
