This choice by Poloniex is a blessing in disguise, i will simply stop trading there and remove all my coins, because it is very shady to pull this kind of BS and cause such panic selling and in turn wipe off a big chunk of a coins market cap. I dont trust Poloniex anymore, i wont give them business.
ascribing motive is difficult, but judging results is not.
their action has wiped out 10's of millions of $'s from the market caps of the companies they just delisted.
that is too much power for an exchange to wield....likewise when they add a coin...generally adds volumes to market cap of benefitting coin. to much power
situation stinks....and imagine the bigger shitstorm that would ensue if they end up reversing decision. market manipulation on massive scale.
