Especially not with the overall thin state of the orderbooks. It has more or less become a frequent occurrence seeing ~10% price swings dictate the market for quite a while now. I find it still a bit worrieng that despite the market having grown significantly throughout the years, the liquidity has remained as poor, if not worse. No wonder that the OTC market has been growing as whale traders still can't settle multi million dollar trades through the current incompetent exchanges.
