Have you tried something similar?, maybe now thinking about doing it?, I think it's a great idea.
No because having all my wealth in one HW seems too risky. I prefer the bitcoin I manage in a HW to be a part of my wealth, and on the other hand I am not obsessed with retiring early. I guess if you have a shitty life and hate your job it makes more sense.
Did you maybe read my post? I wrote something about it, so you could get a much better picture of how much someone can set aside per month for such investments.
I completely agree. I currently save more than that (between fiat savings and investments) but I have to recognise that this is not the norm. I would say that less than 10% of the population can afford to save more than 200 euros per month or so in most European countries.
