What you are seeing are speculative parabolic waves up that break once the buying panic is over. Then the price crashes, dip buyers come in, but there's not enough demand to reach new highs. People who bought during the buying panic take the chance to unload into the bounce. Then volume dries up and the price drifts down to where the buying panic started. Bargain hunters come in and accumulate over time which gradually increases the price.
However that's not to say the price will go up from here. But if I wanted to invest in more coins I would be buying some here. Then more if it goes further down.
