Actually everyone is entitled to choose whatever method that's well suitable for them, but responding based on our discussion and strategies here we don't advise buying low and selling higher if the price retrace up, is actually a gambling strategy were as the possibility of making a profits or losing money is on a 50 to 50 percent chances, perhaps you could be left behind while selling off your investment were as the market will keep shooting up and never give you the chance to buy back again, so perhaps I will just suggest you hold for long instead of chasing the market price.
Those who like to chase market prices are part-time traders or traders who like to take quick profits, even if only in a few percent, and I think you have also suggested something that is not much different from the discussion on this topic because in general here it is more geared towards buying at low prices which then hold them as best we can to see better profits in the future. And the low level of a price can also vary greatly from one person to another, because it is more focused on each person's personal perception.
Currently I can consider the price of Bitcoin as a low price and continue buying with the strategy I have used so far, even though some people may still think that the current price is not that low in their opinion. But that won't change my mind about sticking with my strategy of buying and holding for the long term, because right now I'm not living up to other people's perceptions of buying and holding as much as I can.
