It is acceptable for everyone to buy Bitcoin DCA method weekly, but Bitcoin investment is useful enough according to the person's ability not daily to be self-sufficient. I noticed it started buying bitcoins from November 2020, but I think it is capable of holding for a long time. Because it is possible to hold Bitcoins depending on the situation, DCA method is the most convenient and easy to hold Bitcoins.
A long-term Bitcoin investment can result in long-term sustainability, but the Bitcoin DCA method is most useful on a weekly basis, and Bitcoin purchases are within the discretion of holders.
Why do you only pay attention to Bitcoin purchases since 2020? In fact, Bitcoin itself has been traded for fifteen years until now and if you look at it as a whole from every Bitcoin purchase in the market, of course those who feel the most benefits are those who continue to buy and store it safely in their own wallets without having any thoughts of letting it go even though they themselves have seen more profits from the results of Bitcoin purchases so far. This means that in a case like this, everyone can or may use any method that they think is safe enough and comfortable enough without any burden whatsoever when they want to buy Bitcoin because the goal itself is to buy and store it for the long term without any plans to sell it in the near future.
