It's funny as I was freebaging a few altcoins when your video came out. I don 't know what's going to happen next but I like following Warren Buffet's advice : "Be greedy when others are fearful".
However I think people might lose faith in Bitcoin if the fees keep going up. It's becoming crazily expensive, so it makes it a less and less attractive currency to trade with. So in that sense I think ETH and LTC has a lot of room to grow.
