I don’t believe on this since Bitcoin movement is influenced by many factors including news and technical analysis. It’s very to master the price movements since you don’t when the news will hit the market.

I think holding is the only way to be consistent on Bitcoin since the price keeps growing ever since it was created. Your life will be much easier if you will just hold instead of buying and selling whenever the market make some move because you might loss or missed out once your timing is not sync with the price movement.
