The DCA is probably the best investment method out there but if we are just talking about newbies then there is no questions there, it is by far the best strategy s newbie can employ if they want to invest in bitcoin, it doesn't require having to wait for a particular price range to buy from and it doesn't need a huge amount of capital to start, provided they have the discretionary income to invest with them there is nothing much for them to worry about, they can invest continuously over time across different bitcoin price ranges and that's one of its best qualities, it doesn't care for the price of bitcoin at the time of purchase, over time it will average everything out.
Of course, DCA is a more valuable method for accumulation Bitcoin. Investors who continue to deposit Bitcoin in this way may not experience stress because they are advised to accumulate Bitcoin through their discretionary income or through the additional funds they have available. The amount of funds you are prepared to lose and the savings period you have taken such as 4-10 years will not be needed or you may assume that you can afford to lose it. This is a strategy for prolonging the investment and will not put financial pressure on your family because you are meeting 100% of the requirements for the family and depositing Bitcoin from additional funds.
Yes, is the most valuable method but it require money you will be using to buy BTC monthly or weekly, because you can't invest in BTC and regret in the future. I have benefited from this DCA method some years back, because I did not allow people to discourage me to of the long hodling I applied to the BTC, and it helped me to achieve what other investors cannot achieve in 5 years to come.
I guess a lot of newbies have learned a lot from other people mistakes, that will make them not to invest what will take their life. We have heard many stories about some people that lost money, because they feel they can accumulate BTC in the high price and sell in the low price to make profits, which is what some newbies have experienced from this DCA method.
