Many of these cryptonight coins will seize to exists in few months time, the truth is 99% of these coins are dead already
100%
The chains may still go because seed nodes are active but really most all were forked to print coins for income no matter what was promoted about them or what kind of "development" was done. Some of their values are so bad that they are sub 1 satoshi and even close to one Lsat. These coins are litereally worthless in the current real-world situations no matter their supply. You can literally buy nothing with them without billions of coins and then you have to dump them on an exchange for next to nothing to get BTC to buy anything. Those promoting you can buy things with their coins are just devs selling to devs or devs selling to friends and uneducated persons believing them.
