@JJG, it's all been a long time, on the smoking. I'm probably cold on the exact numbers. Or I just may not want to say specifics here. I used to spend $200 a month smoking, so that was my DCA. I skipped a few times when Real Life called, needing me to spend some Real Money on life stuff.
I am in much better health now. I am blessed with good genes, and I spent too many years trying to kill myself slowly. I've emerged from smoking pretty well. I have some shortness of breath still, but it's getting better. I've lowered my blood pressure from "pop a cork" to below normal, consistently. I sleep like a baby now, I've lost 20 pounds.
I actively dislike cig smoke now.
Wow!!! Even if your number might not be average, it is a pretty good amount to be able to divert into bitcoin - because you figure my estimated ballpark amount was ONLY a bit more than $120 per month if we go with $30 per week, and you would have been getting close to $50 per week - if you were to do your DCA weekly rather than monthly.
I doubt that I need to re-run the numbers, and for sure the numbers look way better if there are more years and more cycles involved - even though at the same time we can appreciate that there are no guarantees in bitcoin, even if it still remains amongst the best of asymmetric bets in front of us.. if we were trying to decide between places to put our money today... ... and furthermore, surely you are getting what seems to be pretty decent health and lifestyle benefits that go beyond the mere immediate financial benefits of being able to put that money into bitcoin.
