People are panicing because of Bitcoin SegWit update at the end of a month and are liquidating their assets until initial period of adoption ends. Market was always volatile but it is dependant on Bitcoin (not talking about daily margins but long term growth). My opinion is that prices will go down even more this month. Deversification is the key tho, and major market cap assets are way to go along the few that are small atm but which have great technology/dev team behind them.
