The dips are always a great time to buy. I suggest looking at the coins performance over the last few days when looking at investing in the dips. If it is a coin you already have and believe in, it’s a no brainer. If it is a coin that is new to you, be sure to do your research and try to determine where it may bottom out. I trade on Bittrex and they make it easy to place limit buy orders that allow you to set the price that you are willing to pay and if the coin gets to that price, your order typically gets filled.
