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.
The trading strategy in your photo looks almost identical.
The reality is more difficult, you know. people just want to do one-way trading, they always think upwards. As soon as there is a slight correction in the market, they get upset and leave the market in fear. This type of behavior is seen only among online traders, real hodlers are never disturbed/upset during the correction period, they just take the opportunity to buy more in the dip.
