There is a important difference during the transition period with fiat-bitcoin competing. Most (even committed bitcoiners) will do what I do:

💯 I will spend fiat, hoard bitcoin until either:

1) I can get paid in bitcoin or 2) when producers of really good stuff refuse fiat

#2 is THE KEY to the transition to the MOE era

Also Hoarding Bitcoin creates incentive to work/produce more to avoid forced selling. This will be true forever
