Poloniex exchange—those few minutes when ZEC was first listed. In the ZEC/BTC trading pair, there was a momentary trade price: 1 ZEC = 3299 BTC. At the time, one BTC was about $600, so this quoted price was roughly $2 million. This is the origin of the so-called “sky-high ZEC price” mentioned by veteran players: the real records from back then when you saw the candlestick chart. I was amazed!
