At what degree of Bitcoin accumulation is one said to be contented, if keep wanting can it be termed addiction
I think it’s a wrong use of word or analogy here.
Wealth doesn’t bring about contentment and that is the case with Bitcoin as well. It doesn’t really matter how much Bitcoin you accumulate over a period of time or how much Bitcoin that is in your possession, it’s just never enough to stop accumulating. Wealth is something you build through a lifetime so long as you’ve got the strength and understanding to keep up with the accumulation.
When you just can’t continue, you can sort out for retirement from hassles of accumulation of Bitcoin or wealth.
It’s not addiction to make money, it’s not a bad habits. Addiction generally is linked to habits that are uncultured or disruptive to individual and societal stability.
