A lot of Altcoin's price is going down but that doesn't mean it will continue that way. This is a good chance to buy altcoin that has a huge potential but finding and investing in a good one is a job you must do by yourself. Make a research on the best coin you will find then invest your bitcoin in it. A dump in an altcoin that you know has a potential to recover is the same as investing in bitcoin that came from a dip.
