Age is not a limitation in bitcoin, I know that an only person might not be interested in reading so much about bitcoin or knowing what's in its whitepaper, so I think basic knowledge or information is okay for them which is how to buy bitcoin, about exchanges and all those little stuff, but when the subject of investment comes in, we know that bitcoin is best approach with a long term mindset, but if they are already retired and very old would it still be a good advice for them to invest long term?
Yes an old person can still invest gor up to 4 years before starting to take profits from his investment, it isn't a must that long term investment must be up to 6 or 10 years but qt least he should have invested up a year of living expenses into bitcoin which can happen in the space if 2 yeaes depending on how much s/he allocated to bitcoin.
O.k..
Let's focus on the old foggie for a bit.. The old foggie who is contemplating whether or not to get into bitcoin, and so, there should be some kind of an expectation that s/he is not going to need the money for 4-10 years or longer, so yeah, the bottom end of that is 4 years, and so how much to invest could be 5% to 25% of his/her investment portfolio.. yet, that may well be lump sum rather than DCA, but if there is a DCA approach, then every time any new DCA investment is made, then the presumption would be that the investment timeline is 4-10 years after any new amount that is investment.
it does not make any sense to expect to take 2 years to invest and to establish his/her position, unless the investment timeline is at least 6 years, since the end of that investment timeline would then have 4 years from the last time that money is injected.
Sure in the end folks can do whatever they like, but it seems that regular investing into bitcoin should be a 4-10 year or longer timeline, and if any person cannot achieve that (perhaps due to age and/or health considerations) then the person may well be gambling rather than investing.
I understand that a more elderly person (maybe in his 60s or 70s) might come into something like bitcoin with a 4-6 year or longer investment timeline, but then maybe some emergencies end up happening (healthwise) that end up causing the investment timeline to be shorter than originally anticipated, and presumably anyone coming into bitcoin in his 60s or 70s has already established various kinds of investment and may well already have various kind of income (or investments that he might already be drawing upon), so a person can still afford to consider that s/he has other sources of income and decide to invest into bitcoin as a kind of supplement (or complement) to other investment sources and still expect that s/he would be drawing upon other income sources, prior towards needing to dip into or to start to draw from bitcoin as an income source, and surely that timeline could still be 4-10 years or longer, even if the person might be higher in age with some uncertainties in regards to health.
