The angel seems maybe to transform into a fallen angel.
Definitely, that can be the best statement that can fully described your recent bad experience with Poloniex and can also be a prophecy for what will happen with this once-popular cryptocurrency exchange soon. Poloniex is destined to be just another footnote in the colorful history of cryptocurrency.
I remember that in 2016, this was truly a known and trusted exchange and many of my friends who got into cryptocurrency had their fist taste of trading in this platform. I am sad to see that it has deteriorated a lot and will not have a good chance of getting back the glory it lost to overeager and more innovative competitors.
We can say that Poloniex is already dead. Unless, of course, a big miracle save it from eventual oblivion.
