because DCA is slow in building your portfolio faster. If you lump sum, buy at the dip and keep your regular DCA ongoing while you use the other strategies once in a while when you can, you will definitely reach your bitcoin target faster than only using DCA method.
I strongly believe that this is dependent on the amount of money you are using to do your dca. If you are using a reasonable amount of money to do your dca, you are going to get to your bitcoin target as fast as you want. If you have the resources, you can dca twice or more weekly or monthly and your portfolio will still move as fast as you want it. All you have to do is just to increase your dca amount and reduce your buying intervals.
Yes I agree with you, people can decide to invest in Bitcoin through DCA and be slow but yet they can chose to be aggressive when there income increases. Afterall there is no place that State that DCA amount is a fixed amount that can't be increased. As a matter of fact DCA strategy gives us the previlege to invest as much as we can either aggressively or slowly depending on our level of discretion and with what we can afford to loose. There are times we might chose to be aggressive in 3 months and be able to invest a more sizeable amount that may well be higher than the amount we chose to buy the dip or Lum some. Let's hypotheticaly assume a person that inve in Bitcoin through DCA strategy with $200 in a week may well invest right around $840 to $900 in aonth. And if he chooses to be aggressive he may well achieve $1k Plus if his source of income is upto $4 to $5k in a month. So this kjnd of persons might not be compeard to the type of person you are referring to.
