so we would not consider things like age when it comes to buying and accumulating bitcoin,
Age can only be a threat to those Investors that can't make direct purchase, I noticed that some people are not familiar with online purchase. Instead they prefer making thier purchase through bitcoin ATM, and if they don't care to learn, some day they will get to a certain stage were they won't have the strength to be going to the bitcoin ATM as they used to when they have not come to aged. in this case they can just consider it as the end of thier accumulation journey, but those who are familiar with the online purchase will not be affected. However i think the best way is to start bitcoin accumulation on time so that before we would get to the stage where we will be facing any of this challenges then we must have reach our investment goal or the stage of overaccumulation.
I believe age here is pointing to health
In my view, age shouldn't in any way affect investment. Things happens (as in surprises/unexpected). To a point as long as someone still has common sense, investment in Bitcoin can continue no matter the age. The issue of using Bitcoin ATM or online purchase is not something that matters so much since they both offer the same result. Come to think of it, what could be the reason why some people are bent on Bitcoin ATM purchase? Could it be because of fear of fraud?
Bending on Bitcoin ATM use is for sure location based, this ATM is not rampant as normal ATMs. So someone who has it located around is tbe one who would be bent on using it, if not the importance of learning how to purchase online already speaks louder.
As for age, surprisingly an elder of say 65 years could still in the next 10 years have what it takes to go to Bitcoin ATM to purchase while a youth of 35 years can not..
Note; aside being located around Bitcoin ATM, incorporation of both purchase means is paramount irrespective of age. Not forgetting the privacy and comfort of the online purchase.
As aged and or unhealthy person, there might be other measures to keep up with investment in Bitcoin. Very hard but it could be possible to have someone who would assist in that regard. Someone who will help in purchasing whether online or using Bitcoin ATM.
Also like you pointed out @ejikeme24 "reaching investment goal" settles the matter.
