oh well , too many pros and contra .
who can be trusted , who cant be trusted , it depend on your mind.
the only thing what i got here is , crypto world is no more than drama .
I often get delisted notifications via email from Poloniex, not only DGB is removed from the exchange, there are many altcoins deleted from the exchange, at least they told me to withdraw the coins to be deleted, they have the right to delete the coins that are in their exchange, it's likely that many traders have begun to abandon their exchanges.
as far i know , poloniex has leaving the CIRCLE , and they seems like reborn, and they also will have a new name, Polo Digital Assets, Ltd.
and i am sure for that reason , polo delist all coin of they think "not qualified"
