Yeah, I do something kinda like that.  Putting a little bit of money into Bitcoin every month is a plan I know about.  I don't put in $500 each month - that's way more than I can afford right now and  and I didn't start doing this 4 years ago either.  But Im hoping that since I've still got plenty of time before I retire early, my smaller investments now will still pay off down the road.  I don't need to get rich quick, just want to grow my savings at a decent clip.
