I've been mulling over this one myself for sure, the upside in holding bitcoin curbs spending and curbs investing but is that a bad thing? I think for a fiat system velocity of money dropping is bad because you have to service debt

In a Bitcoin system, if feel like you spend because you are a net consumer and thats the most liquid thing you have to acquire goods and services or you invest when the market is screaming with a massive premium. 

Right now, that's unlikely but maybe when the market is sitting at multi-trillion trillions and becomes harder to move, you might see Bitcoiners put up some sats to drive deflation in certain markets
