I'm not saying polo are essentially in the wrong, they may need to take these actions to protect themselves and their other customers... but the entire alt exchange system needs to be more distributed. One huge exchange and the rest dealing in crumbs is not healthy. It is open to manipulation for sure.
If you made a fortune on X/Y/Z coin, you would be very happy. You lost out so you're upset, naturally.
That's the risk you take entering the alt-coin domain and when the bitterness subsides, I think you'll agree its part of life, move on and dive right back in.
Could there be more spread distribution? Sure. Will it stop flash-dumping when 1 exchange delists it? I doubt it.
I do agree if you have lost it is part of life and you must dive back in and not be bitter.
I appreciate your point, however your first assumption is incorrect in this case. I have not made a net loss as a result of these delistings. I owned none of these coins other than BLOCK which triggered some buys at just above 10k sats. I am holding those (could be a terrible idea who knows with those guys their track record is not the best but I'm going to take a gamble at this price) but could sell now and would not have lost anything. Besides I'm well in the green on this coin in the last year. Actually trading has been volatile and anyone that was not effected by the intial dumps caused by this announcement would have had great opportunity to make some profit today.
However, I do not agree that if you had 10 exchanges with reasonably equal volume then one of them delisting would move/crush prices like this.
The point is not gaining nor losing as a result of these announcements. The point is such announcements from one exchange should not crush coins by 80-90% when nothing else changed regarding those coins. This power in the hands of one entity that could be abused and provides and even more unstable trading ground that the alt scene already has. We need to iron out all avenues of possible manipulation and abuse that we can.
There is an argument is suppose that if any of these coins has real usage and offer something the alt community needs these coins will survive and come back stronger. If not they will perish or be left to the smaller less used exchanges.
