Have a patience and wait, they will be restored soon and you will have larger profit from it. Do not panic if it is a dip because it will finish and increasing will start again.
You will make a mistake if you don't buy it now with the lower price. Use this opportunity to invest and hold for the next ETH's increasing. Price will be surprising.
I have heard a lot about Ripple and use it for a little bit. It is a new star on the cryptomarket I think and its future can be predicted as increasing of this coin.
Altcoins improve cryptomarket better than the other variant. I have more altcoins than BTC that's way. In my opinion there are more ways to use altcoins.
Buying altcoins is the way to invest so there will be profit if you are ready to wait and have patience. The trading is possible too but I recommend to you holding.
