I'm a firm believer that the world government is behind Bitcoin and with that way of thinking know all the dips are just that. Dips shake the tree of the weak hands and give them and their cronies cheap tokens to sell back to the same people who sold low. Buy when market is red.
Most governments in Asia and Europe are behind helping cryptocurrency. Buying when the market is red is a good thing to do. But depending on the time. Sometimes the red market can last for 4 or 5 months in a row
