Yeah, traditional assets you cannot rely upon a 4% withdrawal rate sustaining itself, but in bitcoin I think that you can, and 100 BTC right now would be more than enough for your goal to have an income of between $160k to $200k per year in perpetuity, even though you are ONLY planning to live until 92. (
look at 100 BTC here)
92 How is it determined whether it is actually taken from a country's statistics? It seems to me that the number of years a man comes to live on earth or how many years he will live, is not up to his own will, it is controlled from somewhere else or God can control it. Here religious sentiment comes into play in many ways, it is the most important factor on religious matters. Ultimately I don't think anyone can put an exact age limit on how many years he will actually live or live. Now the important thing is that if someone is 92 years old right now and he somehow lives to be 100 years old, then we can assume he will live to Bitcoin's peak because maybe within the next 2030 years Bitcoin is going to pass its peak.
