Your asset base should be much higher than your investments if you intend to accumulate bitcoins until you have a decent stash. You can be overly aggressive in accumulating bitcoins but realistically not at the expense of all your wealth. That's why pricing each asset level separately is to ensure maximum utilization during the period of its need. The portion of your wealth that can go into investing in Bitcoin is a fraction of your income and it may take a long time for you to reach a decent size by following the normal process but consistently running it.
Agree with what you just said, when we invest, what we have to think about is how we manage our finances so that we don't get too high, we invest as much as possible, that's fine, but we have to remember, our remaining savings must be more than that we invest, because no matter how much investment is not necessarily profitable in an instant, it will definitely take a long time and be a long process, don't let all the savings we have be invested, wherever we want to take our daily needs, in the end we will end up going into debt first, so We have to balance it with our savings, don't let it exceed the limits of our own capabilities.
it's not a must that your savings or emergency funds must be more than the amount you're using for your investment or in doing your DCA. It's all about setting the right financial management plan and ensuring that you're following it up to the latter.
A practical scenario could be that if you're earning $500 a month and then you could make a simple plan as this; for the first six months, I will
Use 40% of my earnings for my monthly upkeep. =$200
Will use will use 30% for my monthly DCA =$150
While I use the remaining 30% for my emergency funds=$150
If you do this for a space of six months, you should have built a $900 worth of emergency funds which if it's in my region will be enough for most kind of emergency and then you can just add up a $100 to your DCA making it $250 while if it's necessary you can add the remaining $50 to your upkeep money which will still bring it to $250.
Again, this is just a model that works well for my financial level and for your case, you can choose to scale it up to 2× or 3× this number and it will still work well for you but the essence of seeting out stuff like this is that because you're setting out an amount that's not going to take you too much time before you eventually approach your accumilation goal. As your finance grows, you can always modify the amount that you're using but the summery is that you shouldn't always assume that your DCA amount must always be small just because you're investing for the long term. Be wise enough not to over invest above your capacity but don't also use that as an excuse to underinvest.
