It's just an intermittent cycle that scares a lot of people. Some whales decide to pull out their money, so they do and the prices drop. More whales follow. Then, the initial whales who pulled out decide to buy at this newer low price and start making the price go back up while all of the other whales follow. The price continues to rise because people are buying after the drop. This will continue for a while; don't doubt it. However, there are more players in this game getting involved now, meaning that there are more whales which can end up being beneficial for the average user here on out.
