maybe it's more advisable to allocate their funds on non-passive investments, what means they won't have a source of automatic profit, but at least they can pursue superior returns to maximize the potential of their money to generate further monthly income.
Why it is necessarily? I mean you may go investing on a passive stream and from that you may go DCA with bitcoin and you still get chances to maximize your wealth. After bitcoin, honestly I do not look for any other investments which may provide passive income or automatic profits. I just believe into bitcoin and saves it for my retirement. From bitcoin investments, like you mentioned that I am not getting any immediate returns.
