Bitcoin investors especially those new to the market just need to understand that price does not just move in one direction. It takes correction and retracement waves to decide which trend is likely to dominate,  which is the simple principle applied in Elliott wave theory. A good technical analyst might sell now and have a good entry point to buy that is if the bought at a more cheaper rate earlier. But for new traders who are not conversant with the market enough it might be risky selling because the might not know what price to buy at and when to sell so they simply hold.
