The purpose of DCA is to invest regularly according to a set plan without guessing the short-term fluctuations of the market. If someone looks at the chart every time and thinks that the price will drop a little more and then buy, then he is trying to time the market by moving away from the original DCA method. This is much more uncertain because it is not known in advance whether the desired price will come or not.
Chart analysis may be necessary to predict the price of the market next week, but as a long-term investor, you do not need that kind of trading analysis to understand the fundamentals of Bitcoin, volatility and your own financial risk. It is more important to understand your cash flow, discretionary income and investment time frame without putting a new investor under the pressure of learning charts like a trader.
DCA is a system where an investor needs to check his own sources and limits before investing instead of checking the market and having any analyst because it already has everything for investors, so never do anything for a waste of time; just jump and start your journey with your set goals because this will help to have good end to your journey without having any problems but having a long-term strategy always gives good results and profits.
Other things are always important for trading or having short term things but in long term when someone is already set mind to stay with DCA never needs to be worry about his investment because Bitcoin is having enough potential and its never been regrettable for anyone who is going to stay in bitcoin with this always needs to learn about fundamentals and risk management give extra peace in mind because its also part of having knowledge of bitcoin.
