and polo will be scam cause waiting approval more than 48 hours
Please let's not scare others with the issue of poloniex as scam. With the little issue you encounter, you start to accuse them as scam.
maybe you don't label then as "scam" because they might not use your money for their personal benefit (at least I hope so). But one very true fact is that they froze and block the funds of thousands users.
then end is the same as a scam: you lost your money
poloniex is dangerous to use due to their frequent automatic accounts locking, and total lack of support to reopen it
