Although basically every individual has freedom in terms of Bitcoin accumulation and it does not rule out the possibility for them to do an aggressive way like you said with such an amount, but in my opinion it is not a good accumulation if they do a way that can suppress (force) them in terms of their finances, even though their goal is quite good to master 1 Bitcoin, but honestly I would not really recommend this method to anyone unless indeed if you are one of the conglomerates who have an income far above average and with a DCA of $100 a week is not at all burdensome and does not interfere with your basic needs then go ahead. But in my opinion on the other hand this is still not a good alternative, because obviously if we look in terms of time then it will still take a lot of time for you to achieve success to reach 1 Bitcoin, and also on the other hand time will continue to run, meaning that as long as you do this method it is very likely that there will be changes in the price of Bitcoin, if bearish dominates when you do this method until completion then it is a little profitable, But if Bitcoin is rising due to factors such as halving, it is likely that the amount of money you have to allocate will increase and with that means that in terms of time it will also definitely be longer if you put a flat amount ($100) on each DCA you do.
There must be a good strategy in this case even though the goal may be very good to do but when the method only makes ourselves difficult in the end this can hinder the pace of DCA done.
$100 per week will indeed provide greater benefits because what we invest is very large but on the other hand it goes back to the initial problem of whether we can do it consistently for a long period of time? If in the end you can do that and with the support of the benefits you have from the salary you receive every month to be able to invest $100 / week and be able to cover other needs for daily life, it is indeed very good but if we have a modest income and investing $100 / week is draining your cash I don't think it's worth it even though your desire to get 1 btc is very good but in the end when impulsive methods like this are done, this will destroy your desire to get 1 btc because of your difficulty in managing your finances because you are too pushing yourself for the goals you want to achieve.
Keep in mind this is an investment for the long term so when you force from the start with a big start then when you have problems in the purchase made because it is too burdensome then this is precisely what becomes a problem so that the investment that is carried out does not go well.
