Buying every dip is easy to say, but difficult to identify the dip (for me at least!)
Every time the price of bitcoin drops I am afraid of the point that it is going to stop or it will be ongoing for a long time. Looking at charts and trying to make my TA sometimes prove me wrong!
there is nothing difficult to identify a dip you see it that way, because to me every buying is dip, as far as your plan is long term holding, bitcoin has has not yet gotten to it final spot, it's still growing and increasing in price continuously that's to tell you that bitcoin can increase in the future above the price you bought it at that time, so your mindset should be long term holding and not for short term and don't sell when your investment have not yet matured if not you be lost.
Waiting to buy the dip will only miss you out completely because you don't know how long it will last and then bounce back above the previous prices, the dip only helps investors to accumulate aggressively either using the DCA, lump sum or buying the dip strategy, it gives investors the opportunity to buy more and the new investors to start accumulating and HODLing for a long-term of 4-10 years.
