I'm not a fan of these centralized exchange coins. In my eyes any regulation of these websites, or the county they are based out of will cause massive havock on the coin. If KuCoin is ordered to hault transactions immediately by government order, what's the worth of the coin. I just don't see it. Also these rewards for holding coins seem very ponsi-esque to me since I don't see a utility other than holding them to get free money. I'm a skeptic, not trying to trash KCS.
A good point, it is only a matter of time before crypto currencies and exchanges are regulated and the outcome is anyone's guess, there will be a safe haven somewhere and the top exchanges will register when the day comes.
As for the worth of the Coin/share its simply only worth what the next person willing pay for it. There are people out there who bought BTC for $20k only to find the next person didn't see the value in it, they have either got out with a small loss (perhaps profit) or are sitting on a coin worth about 50% less value.
