For now 3 stars
My experience was good, withdrawal of a delisted coin and deposit went smoothly. Then for a 2nd time a coin was delisted and I wanted to withdraw but it was not possible. I had to finish advanced KYC first which is good so Poloniex knows who I am. What a disaster the advanced KYC. ID card front and back went smoothly but the live ID face check was failing, failing again and again. Too far away, too close, blink with your eyes. It looked like camera distance is millimeter work... Different light positions, different backgrounds.....I did it about 20 times but every time check failed message. I was worried, what if they never accept then my assets are stuck and lost. Now again failure but the 4th time it was accepted. In other reviews people complained the customer service did not reply. My experience is positive, they replied within one hour ! It was a standard copy and paste message, change light, change background but they replied very fast.
