Ethereum bounced back 40% on Monday after seeing the price fall to a low of $130 on Sunday.
Two factors that may have caused the fall below the psychological $200 ETH price, the ICO effect is still being understood with companies selling their ETH (which could vary by company) and the simultaneous fall of Bitcoin's price. BTC had a large effect on many of the cryptos over the past week.
ETH for the year is still up over 2000%.
