And at today's prices, accumulating between 10 and 50 BTC seems like it could be in the grasp of a lot more ordinary people.
On the other hand, if a person lives in a struggling situation, then maybe at most s/he would be able to reasonably accumulate 1 to 5 BTC... in these $200 price territories.
Your targets are very high IMO. 10 - 50 BTC, $11,000 is more money than I would be comfortable losing if everything went to zero. 10 BTC ~ $2,000 is also a little tough, I wouldn't be happy losing two grand but it wouldn't be catastrophic either. At least just about everyone can dig up $230 and buy at least one coin. So right now is a great time for new comers to join in, buy a coin and stash it away for a few years.
The point I am making, is NOT only about you and your personal circumstances and your view about the future of Bitcoin.
Surely, a person should keep in mind that s/he could lose the BTC whole investment based on his/her view of probabilities.
Let's say for example, a person viewed probabilities like the below chart of probabilities for a 5 year time-frame:
less than $200 < 5 % chance
$200 to $300 about 5-10% chance
$300 to $500 30-40% chance
$500 to $1000 30-40% chance
$1000 to $5000 12-18% chance
$5000+ about 5% chance
Someone like this better be putting a whole hell-of-a lot of money into BTC because s/he sees the 5 year time frame to be of about equal chance that BTC will be worth more than $5,000 as it will be below $200. therefore, the outlook suggests to invest quite a chunk of your investment assets in the direction of BTC.
On the other hand, it appears to me, that you, coinableS, are giving a much greater probability that BTC is going to go to zero. maybe your 5 year outlook is something like this.
less than $10 - 50-60 % chance
$10 to $100 about 20-30% chance
$100 to $200 5-10% chance
$200 to $300 5-10% chance
$300 to $500 <5% chance
$500+ < 2% chance
If your viewpoint is something like the above chart, then what you are saying makes sense; however, I believe that the second chart that I made is overly pessimistic about the future prospects of Bitcoin, even though each person is entitled to his/her own view point and outlook regarding BTC.
My view is probably closer to the first one, and I imagine, coinableS, that your viewpoint is NOT quite what I made it out to be. If you disclose your viewpoint about probabilities, then at least we will know whether you may be investing in accordance with those viewpoints.
The question about how much a person has to invest into BTC can also be calculated based on how much income stream and then making an assessment of the person's distribution of those investment assets and risk. I do NOT advocate putting all of the eggs into the BTC basket, though quantities of 1% to 20% could be considered reasonable, depending on a person's view of probabilities (back to the above charts or some variation of such).
