Tmoonz is still of the opinion that newbies in bitcoin investment should invest in bitcoin within their discretionary income, but they can increase their investment allocation if they improve their income to a better one along their bitcoin accumulation journey. For instance, let's assume a newbie in bitcoin investment is earning $100 monthly; he can decide to be investing $10 every month into bitcoin with the DCA strategy and use the remaining $90 to solve his monthly expenses and be building up his emergency fund, reserve fund, and floats gradually. If the newbie gets a new job along his bitcoin accumulation journey where he is being paid $200 monthly, he can now decide to increase his DCA allocation money to $20 monthly since he now has more cash flow that can take care of his monthly expenses and build up his emergency fund, reserve fund, and floats while he is using $20 to accumulate bitcoin monthly.
In summary all you are trying to say is that newbies should invest according to the level of income that comes their way hope I got you correctly? I think the same thing is applicable to both old and new investors, do not invest beyond your financial capacity you will end up being emotionally unstable, good to see that you gave a very nice example but I think for someone who is earning $100 as a monthly salary you can decide to go with $20 as your investment budget that's if you won't be affected by other things that requires your finance to be taking care of and if you are promoted and your salaries increases you can decide to increase your monthly investment amount or continue with what you started with. One thing with the DCA method is that it helps the investor to spend wisely and it gives you the opportunity to purchase Bitcoin any given time so even then you are yet to receive your salaries if you have a little deal that brings you money you can decide to purchase Bitcoin instead of spending the money on material things.
Investment rules don't apply to newbies alone it cut across to all investors both old and new, it's all about investing rightly within ones financial capacity with which they can be able to survive with what's left after removing their investments funds from the total amount they earn in either weekly or monthly.
Another thing which is my personal opinion is that the amount with which we invest with monthly doesn't necessarily have to be static. As in, you can decide to invest $10 this month and probably put in $20 the next month thereabout depending on how things turned out to be for you financially within the previous month. Because there's a way you can spend frugally and do have some extra bucks left into the new month.
I understand what you mean by not investing with a specific amount weekly or monthly but that is not of our own doing, because it's your discretionary income that will determine how much you are to invest in bitcoin every week or month. For instance, someone with $12 discretionary income will not be able to invest above his limit. Such person cannot invest $20 or above $12.
However, I know that sometimes, our weekly expenses varies from week to week which makes it possible for you to invest with the left over after taken care of your weekly expenses.
