A couple of years ago when cryptsy.com was around i invested in several coins (Ether,Bitcoin, Dogecoins ect). I had over 1 million Dogecoins in their exchange and 1 million Earthcoins before the owner Paul Vernon decided to steal everyone coins and flee to china. Thankfully i saw early signs that the exchange was going under and decided to remove my bitcoin and ether. There is a class action lawsuit against Paul Vernon that i will be participating in. i lost all of my Doge and Earthcoins after leaving my coins in that exchange. I learned to never leave my coins on an exchange unless it is for trading.
