you actually right, back then i focus on buying in dip most time end up missing out because all my target was when the price is low I will buy and sell when it's has risen to a certain profitable price but never do me any good because always miss out ever since I started using the DCA strategies I've seen my portfolio increasing even when sometimes market experience some corrections, I don't panic at all I just take as opportunity to buy more.
When practicing the DCA strategies the chances of you missing out pretty low
What you were doing was trading, buy low and sell high. Sometimes you will make money but most times you will lose. Buying the dips for short term trading is not much different from gambling, like you already said, you will surely miss out sometimes and the losses will never depart from you.
Buying the dip for long term investment is not a bad way of Bitcoin accumulation, it is definitely a nice way of getting decent amount of Bitcoin at discount price. The problem I only see in buying the dip is that it could be very tempting to sell when the price finally goes higher and seems to have stalled even if it is just for some moment. The investors might face the temptation of wanting to sell in order for the price not to dump and return to below the major entry points. It will really be painful for the investors to buy the supposed dips, see good profits and still allow the price to go back below the entry point, this might lead to some form of regrets.
When an investor is ready to overcome these thoughts and drive that is associated with buying the dips, then it could turn out to be a very good approach to Bitcoin investment.
