Oh I don't know dude, how about a medium of exchange?
Some days I wonder if "store of value" is what I signed up for when I started working with Bitcoin. The idea at the time was to be able to collect payments and buy stuff using something other than Paypal and dollars.
Now.... Still use it for that, but it's more complicated.
Get out of here (notice the absence of an expletive) with that medium of exchange versus storage of value false dichotomy.
Do whatever the fuck you want with your bitcoin, and if you think that there is some other preferred medium exchange, buy some of that.
The development of bitcoin takes time, and many of us know the expression that if a better mouse trap is built, then peeps will come to buy that mousetrap.
There is no better mousetrap than our little friend, aka bitcoin, and who the fuck wants to spend it if it is likely to appreciate in value.
Of course, you can spend it and then replace it, if that is what you chose to do, but it is not like we are absent other mechanisms to pay for things, such as fiat? or bcash? or ethereum, or some other non-appreciating asset/currency? if I used my credit card, I earn points.. If I don't have a credit card, then maybe I will spend my bitcoins if I don't have any other way to transfer value, but most places have fiat.. and if that fiat is depreciating in value, you gotta find some place to put your value.. bitcoin? or some other more stable fiat? or what? gold, silver or some other PM? I prefer bitcoin, personally.. it is more portable and gives me a sense of empowerment in terms of managing a decent portion of my own accumulated value/wealth.
