All you have to do is buy and buy and buy altcoins that has a big potential to growth in profits when the situation of going down is over . Buy bitcoin and etherium because this two has the biggest potential in gaining a lot of profits when their price is back to their normal state, now that this two cryptocurrency is in dip , its the best time to buy them and hold them.
Yes the best thing to do in this fallen price is buy more crypto, but it's too risky because no one knows what will be happen, if they rising again or going to the end. In this dip I buy and other altcoins that I can afford.
