It is funny, if you save money in USD it is called saving, but when you do it with BTC it is called "hoarding". Is there a more negative word we could have chose to replace "save"?
To save BTC is smart as it is a deflationary currency. I think where people get lost is in the assumption that we should only spend it, but that is consumerism. I think a smart thing
to do is to save as much as you can (just like in general, don't be a consumer) and when you have the chance to buy something with BTC, you do it! Moving money out of fiat and into
something trustworthy (not necessarily BTC of course) is smart as the printing of money and the way the banks are run is theft.
Because BTC is so divisible (8 million bits per BTC), even if the float was decreased MASSIVELY it wouldn't matter, there are still plenty of "bits" to go around. I think I heard something like we have
enough Bitcoin Satoshi's to have one for every penny in the money supply, something like quadrillions.
