If you have 100 btc at a cost value of 1k each you just sell 2 or 3 a year if you are 67

you have corn till you are 100 or 133.

if you have 100 btc at a cost value of 1k each you just sell 1 or 2 a year if you are 50

you have corn til you are 100 or 150.

my point is if you have 100 btc at a cost value average of 1k a coin  trading is not needed .

you can spend it even if you are 40 and spend 1.5 coins it takes 60 years to spend it all.
