Absolutely. With Bitcoin too, it went crazy down in April due to fear of BTU, but now mid-may it's crazy high. You gotta have patience and trust the coins you invest in. If you don't trust the BTC or altcoins, do NOT invest in them.
ETC, ETH, XMR, XRP and LTC are the best coins to trade at a moment and even if price goes down do not panic and hold them till the right time comes as if you get panic then you will be surely selling your coins at huge loss.
