According to what I have learnt so far the reason for DCA is to relieve or save yourself from the stress of not knowing when to buy, since bitcoin is volatile The practice changes at any given time so now the DCa help you to buy
Btc at any given time basically weekly. Sometimes you
May buy when the price is low and also by when the price is high. When you buy in some week it is low you are indirectly replenishing the lost value when you bought higher. So DCA is the best sofar in investment strategy it's a middle man between dip and HODL and lump-sum.
DCA is definitely a great collaborative tool, but it's very difficult to use it properly. The reason is that most people make mistakes in regular investment. In this case, it seems to me that there is no problem with the DCA method, the problem is with our decision here.
In order to invest in Bitcoin using the DCA method, you must first have an income source. If you don't have an income source, it will be difficult to hold the investment for long. You spend the money you need and invest some of the remaining money in the DCA method on a monthly or weekly basis. You should continue investing with DCA method for long time. You will invest according to your ability. If you can't invest long time with DCA method then you won't be successful.
