You're lucky. I had to learn this the hard way.  Sharks decide where the price of most coins move.  Everyone else tries to "time the market". One of the rules of investing, is to never "time the market".. this is moreso true when the markets and data are manipulated.

Everytime you buy a coin, there is 5-6 heavy whales on skype or some other platform talking to each other saying things like "Ok, want to raise the chart on this coin? Where's our high at? When are we dumping it?" it's all collusion. If you follow the graphs as your sole source of information, you will be in trouble over the long term.
