the market sometimes goes down and at that time, those who do not invest have the opportunity to invest.
The dca method allows us to invest with out firstly waiting for the price of bitcoin to go down before buying bitcoin. Those who actually waits for the market to go down before buying are mostly traders, investors invest in any market conditions they don't wait for the price to drop before buying for example you might be targeting the price to drop below $90 before buying and your expected dip do not occur which means you won't buy meanwhile the purpose of the dca method is to buy bitcoin at any market condition be it low price or high price, this will also make you stack enough bitcoin because you are consistently in the market buying without waiting for any dip when ever there is dip you can decide to buy aggressively without overly doing it and stack more bitcoin and hodl for period of 4-10.
The price of Bitcoin always fluctuates. If you wait to buy at a fixed price, you may not get the opportunity to buy Bitcoin at that price, which may hinder your Bitcoin investment in the future. And DCA will save you from such a situation. Whether you buy at a low or high price, your average purchase price will be relatively low. For those who do DCA, buying Bitcoin also relieves the human pressure. For investors who buy Bitcoin for trading purposes, buying at a low price and selling it at a high price will relieve the DCA holder from the pressure that is created. DCA holders can accumulate Bitcoin without pressure. Surely, those who do DCA will get the opportunity to stack Bitcoin on a weekly or monthly basis, which will turn into a large asset in the long run. If an investor wants, he can deposit a certain amount of Bitcoin regularly through DCA and if there is a dip, he can also buy more according to his convenience. Those who are new investors or those who are not able to invest a lot at once can easily increase their Bitcoin savings by investing a portion of their discretionary income with DCA.
