As you know, one of the most popular kinds of manipulations on the cryptocurrency market. Big players on the cryptocurrency market are known as whales. They can manipulate the cryptocurrency price using the tactic “Pump and dump”. Whales buy a lot of cryptocurrency in several days causing price increases. This attracts new investors to the cryptocurrency because hamsters want to buy more cryptocurrency in hopes that the price will be raising and they will be able to sell assets for the higher price. But this isn’t happening, because whales, after gaining a specified mark, begin to dump coins. In such way, whales get a profit, and the price of the cryptocurrency falls. How do you think how not to become the prey of such kind of whales` manipulations?
There will always be manipulation in regard to markets. Company stock price can be manipulated in a similar fashion. We saw this recently with Facebook stock. Company executives sell off their shares and FB stock drops 19 percent in one day. Though they likely violated law by doing this, it did not stop them from doing so (don't hold your breath waiting for anyone to be prosecuted.)
Consider whether a coin is overvalued. To some degree, you have to go with your gut. If a quick, steep rise occurs, question whether there is a legitimate reason for this or if it is most likely another pump and dump scheme. As you stated, these patterns are usually predictable.
