Exchange token is good to buy, while hold for a long time and among all exchange token been mentioned, I prefer investing on Kucoin and is good to buy and they are more reliable to invest in cryptocurrency market, while expecting big whale to come in the near future.
In my opinion, most exchange based tokens have done exceptionally well, especially those whose exchanges are still waxing strong with good reputation. I have not heard much investors of exchange based token complain or regret investing in such tokens and that is a good sign for me. Even though I have not invested in them before, they are good option because they are supported by real product which guarantees that they do not become worthless.
If I want to consider investing in exchange base token, KCS will likely be my top choice for several reasons which include but not limited to Kucoin being a reliable and innovative exchange with large customer base.
