That's a good start when you aren't comfortable enough in life. I think $10 a week is very affordable. Consider it a long-term investment, maybe over 20 years if possible, as you never know how much it will grow during that time. We do spend on our personal wants, so I believe we can minimize expenses and redirect that money into investing in Bitcoin.
Starting with $10 per week does not mean you must remain at that level for 20 years. That is an anomaly as we all aspire to grow in finances. Besides, it is at the current price of Bitcoin, $10 per week will really require so much time to realize a life-changing portfolio as I do not see Bitcoin doing X1000 easily. Therefore, to start with $10 per week requires that plans should also be in place to increase the inflow so that it will become easier to get 1 BTC which I consider something reason to hold for the future.
Due to market inflation and various economic factors that might change in the long run, I guess it's good to have an interest in long-term investment. Some people quickly dismiss investing in Bitcoin because they want to own 1 BTC right away, but when they realize the price of Bitcoin is not cheap, they change their minds. So, this weekly commitment to investing in Bitcoin is better than doing nothing at all.
Based on my calculations, if you stick with $20 a week, you would end up investing $20,857 in 20 years. However, the value you'll be holding at that time is likely to be higher than that. So, if you were to get a 10x return on your initial investment, that's $200,000, which I think is a good outcome compared to not having that money at all. The $20 was just a sample amount, though. You can always go higher, take on more risk, perhaps invest $100 per week or more. Since we can make our own calculations and predictions, our target should be something that we find fulfilling.
I don't see $10 per week as a bad start for a newbie because he just started his bitcoin journey and that will even be more easy for the newbie to afford regularly so that he can continue with his DCA strategy. You should also consider the cash inflow of that investor. I believe that the money that one uses for DCA should be based on his income, so that he doesn't use more than the amount that will affect his plans on accumulating bitcoin regularly.
If as time passes on, income increases, that's fine, because as an investor, you need to look for other ways to increase your income, in order for you to also increase the amount that is used for regular DCA. This is because it is better to take advantage of increasing your bitcoin portfolio when you have the opportunity. On the other hand if the investor income did not increase, and he didn't see another way of increasing his income, then it is better that he continues with the $10 regular DCA.
Since that investor plans to accumulate for 20yrs, I believe that he will be happy at the end, because he can smile and look at his investment portfolio, disregard how many bitcoin he was able to achieve within these period of time. What I believe is that any investor that has planned to hodli and gradually keep increasing his bitcoin, will get to a time that he will want to increase the amount that he uses for his weekly or monthly DCA, if he can afford it. This is because the more you are getting used to accumulating, your faith in bitcoin will keep on increasing, just as your portfolio is also increasing, because you will keep on understanding the market, the value of bitcoin and you will be happy that you are securing your future.
It is better that you use an amount that you can afford till the end of your accumulating timeline, than you DCA aggressively and something comes up that will make you go and sell from your bitcoin to solve that problem. What I mean is that it is only us that knows the right amount that is easier for us to use for DCA, as long as we don't stop accumulating or get discouraged in accumulating more bitcoin to our investment portfolio.
