My guess is not very many.

At some point I feel like some folks will be ok with reallocating a portion of their portfolio to something other than Bitcoin. The value & reasoning of this diversification would be non financial in nature though.

Quality of life improvements or hedging against meatspace risk is the driver I see them being interested in.

If borrowing against Bitcoin becomes more common & less risky, it would change things though.

I think Bitcoiners are generally quite aware & averse to risk.
