I don't think that they are worth holding. They are totally related to an exchange, and if something happens to it - the token will die too. This might happen even in calm times or during the bull run, you never know what's happening behind the doors.
All of exchanges coins aren’t bad, as like BNB is the backed of the number one crypto exchange Binance. So, it’s fundamentally strong coin, early investors got big profits if considering others exchanges coins. Still i think it can be worth investment, although recently a bad news coming so it’s started dumping but i think it’s a promising coin for the future.
the exchange still remains a large monopolist, and this may mean that nothing threatens the exchange token in the near future. Quarterly token burns will do their job, we need to wait a little longer and see how the price reacts to this event.
Some big exchanges native tokens just surviving based on their exchange reputation otherwise there are no real use cases of those tokens such KCS is backed by the major exchange KuCoin but you can check it in CMC, very low interest in trading only 1m dollar trading volume. Only BNB is in strong fundamental coin and it’s a lot of utilities in the market.
When it comes on holding exchange token then this is something that would be still a gamble. We dont know if a certain platform will really be able to make themselves on the top.
Lets go back into the time that BNB was so cheap but there are lots who had that simply ignore and sticking into those known sites which are known on that time.
For those who had risk out their funds with BNB then it did become that top ranking exchange platform then it did really make out that huge reflect into their own native token.
This is why i could say that it is really that needing a little bit of luck when it comes to holding and choosing on which coins.
It is really hard to determine or hard to know on what would gonna happen next into this market. If you do see a certain platforms that has the potential to become
the next Binance then it would your choice whether you should invest or not. Everything will really be that depending into your risk taking since
not all does have that the same tolerance when it comes to risks.
