DCA method is not only for long-term investment but also helps in accumulating more Bitcoins, it is a suitable method for long-term holding in all aspects, which is why DCA method plays the biggest role behind the holding of every investor. When you start holding Bitcoin and if it is every week or month then you will be busy raising money and will also get rid of extra expenses. For example, citizens of every country may keep money in their domestic bank but they get low interest, but Bitcoin is such a coin where if you deposit Bitcoin, you will be ready to get your maximum profit within a few days.
You should note that the history of Bitcoin price is right. Those who have invested in Bitcoin and have held their Bitcoin till now are present to get the maximum benefit of their Bitcoin. For this reason I say Bitcoin is the only trusted coin in which all people can be successful by investing in it in a long-term manner.
DCA increases our focus to keep buying, if we routinely buy every week then when we miss it once it feels like a regret and that's what can be said if DCA is comfortable then we will be more focused on accumulating bitcoin.
If you are a consistent DCA method user, you will always want to keep buying Bitcoin no matter the current market price of Bitcoin, I do not know how some people run their own DCA but if you buy weekly and you happen to miss in some cases when you don't have the funds to buy you can decide to use a double of the amount you use to cover up the times you missed the previous week. You may not meet the price of Bitcoin the same way it was in the last time you missed out but being comfortable in your investment is the reason for choosing the DCA method cause you will always have a good reason to keep buying knowing that you have got nothing to lose if you are consistent with the method. Do not regret when you miss a few weeks just try to double the amount you buy the next week and keep accumulating as much as possible.
I agree with you that if you miss out a week from your regular DCA purchase, there's no need for regrets but look for a way how to make it double when next you have the funds to double it in order to cover up for the missed one. This is because sometimes our expenses are not always equal, it can be higher sometimes and lower sometimes. If you come across an increase in expenses that might devour almost your discretionary income, you can skip buying bitcoin that week and make it up whenever you have a low expenses week or month.
Sometimes, it might be that when you are expecting your income was delayed, that doesn't mean that you when it comes, you ignore buying double. I could remember when I got paid a week late than usual and I use weekly DCA to accumulate bitcoin. The next week that I got paid, I immediately bought double the amount I am supposed to have bought for that week to cover up the missed one. Everything is just you planning and figuring out things based on your own financial situation playing around you at that moment.
My friend was in a remote area without an internet and couldn't buy bitcoin for two weeks when he was over there. When he returned, he came to me and explained what happened, I only advised him to DCA for the weeks he couldn't have access to the internet and he was cool with the answer he got. He was lucky because he had the funds intact. You can also frontload your investment if you know such situation can play out and have the funds to frontload.
