you are likely to want to spend it and would want to look for spending in a way that has the least friction, instead of selling on an exchange you'd rather do a direct exchange for goods and services
This friction point was my favorite insight of the article. We will shift to using bitcoin as a medium of exchange if/when we begin accounting for this friction.
It also implies the path to new money is niche store of value -> niche medium of exchange -> store of value for more people -> medium of exchange for more people and so on.
I have been using Zaprite and I think it's a great tool, It makes it so easy to invoice in Bitcoin, and I wish more people would take me up on it
I've only used @zaprite on the paying side, but I remember the first time I used it and being genuinely impressed ... I had to praise @john immediately. It's self-sovereign in the most important ways and dead simple to use otherwise. It support fiat payments now too if the buyer is unwilling to use bitcoin.
