There's only one problem with this "dip". The bottom may be even lower and the price after the purchase may fall even lower. The price of many altcoins drop down 10 times or more. So it is unclear where is the bottom? Even such a stable coin( I thought that way) as ETH lost in price very much, as to talk about other altcoins. So buy in this market is extremely dangerous, can experienced traders and come out with a profit, but I'm still in the red.
