Many people think that bitcoin should move up in a straight line but this is not how the market works. Markets may show us many up and down before moving up and sadly people are not ready for these movements and sell their bitcoin before it reaches the all time high.
Any trader or investor that has been in the market for some time will certainly understand that this can never be the case unless they just want to lie to themselves and might continue to lose money in that sense. Every financial market does have all the sides to price, up, down, and sideways and when you fail to understand this, then you are setting yourself up to fail.
