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.
This is why you need to put a strategy to reach the bottom just like you should be divided your amount in a lot of partials and then you can try to minimize the risk to get the bottom price. When you are only putting 1/10 of your amount while the price of coin stuck on 900 satoshis and then if that will go even lower and you can try to put the rest.
