Manipulation is here, there are clearly heavy hitters in the market that control the direction one way or the other.The big exchanges are giving investors an unrealistic picture of the market. The average traders tend to assume that the majority of trading happens on exchanges. In reality, the very large investors trade OTC, so a significant amount of volume and pricing data is absent from exchanges. I recommend spend in small amounts and replenish as you go. This is the best thing for bitcoin. Try to Avoid centralized exchanges.
