The price of bitcoin will definitely increase but as it increases you can participate in bitcoin investment. Because if you don't participate in Bitcoin investment, you will not get any benefit if the price of Bitcoin goes up or down. So since you are new then surely you can participate in bitcoin investment and use DCA method in it. If you hold Bitcoin for a long time with DCA method you will be ready to get more benefits, only DCA method is quite useful for both new investors and old investors. Low risk and high profit is possible only through Bitcoin investment, so you should follow DCA method in Bitcoin to keep you investing in Bitcoin and keep it for long time.
Do not underestimate the lump sum strategy and the buying the dip strategy by saying that the DCA strategy is the only useful method of accumulating Bitcoin for both new and old investor, you are simply saying that other methods of accumulating Bitcoin is useless that is wrong mate all the method of accumulating Bitcoin is useful in one way or another investor chooses to make use of the method that works for him.
Some of the things @Popkon6 said is true but however his understanding about other various investment strategy is not right because he feels that since DCA is commonly used by new beginners including him that's why he disregarded others and from there he draws the conclusion that DCA is the only useful investment strategy, though if he had tried other strategy he wouldn't have said that because there are three different strategies that has been explained here and we cannot exclude the importance it all has if an investor uses them.
However before those different types of investment was even introduced here most other investors has already been using them sometimes which is Lump sum and Buying at Dip on there accumulation of Bitcoin, so perhaps for the higher use of DCA strategy shouldn't mean that every other Bitcoin strategy is bad, so actually @Popkon6 was wrong on that narrative. So in other words the tree strategies is like embarking on a journey that has only three ways of getting to the destination with a very lesser risk on the way but however even if the majority of people focus more on one way doesn't mean that other ways will not lead to the destination because at the end they would all arrive at the same point, so actually this is just another way of explaining how important each and every investment strategies is.
