If we invest excessively, our portfolio increases but spending every month will be burdened because a lot of money goes out to bitcoin while other needs are cut because we want to increase investment every week or month, of course this will be heavy and unbalanced people will definitely find it difficult to do this.
There is no need for one to invest on whatever will be a burden on him, because an investment should be something that is tension free and burden free since you are on a long term ride. The lesser the burden on you when you are DCAing regularly, the higher chance that you have to invest in a long term to achieve your goal.
It is good when an investor on a long term bitcoin accumulation journey is sound in financial management, this will help him a lot to be flexible with his bitcoin accumulation in various stages of bitcoin price, and he will continue to accumulate more bitcoin with regular DCA irrespective of bitcoin price without a problem, because he has a target that he wants to meet up with, even though it is within the duration of 4-10yrs.
