One thing thay I love about the DCA method of bitcoin accumulation is because it allows you to buy with very little amount and pile it up overtime before you know it you will be surprised at the size of your bitcoin portfolio. Slow and steady wins the race is better than waiting for the dip that may or may not come.
This is the method that I have being using to accumulate bitcoin for sometime now and it is really effective because i do not expect I could have this size of bitcoin that is in my wallet assuming I didn't use DCA because I am a low income earner.
This is such a great point, I mean if you just do 50 dollars a month, that would be 600 dollars a year, and in 5 years that would be 3k dollars, with some increase in bitcoin you have more than 10k in most cases, that's a good enough money as a capital for most things.
You want more? In bitcointalk, you could literally make 50 dollars a week in most campaigns, do not consider that as income, keep it in, that would be 2600 dollars a year (52x50) and that means in 3 years you would have 7800 dollars, with some increase that could be as high as 20k or more, in 5 years that could be near 50k if bitcoin goes well with next bull run as well. So, when you invest just a bit, it would be insanely good overtime because of the accumulation, you never put too much at once, but it collects to be huge.
