I don't buy a lot of things on Amazon but whenever I go to my purse.io to buy something I have just about the same dollar balance that I had the last time I bought something.
I like this magic Internet money.
That's nice to hear, although you won't feel so good when you calculate how much the BTC you've spent buying Amazon stuff are now worth...
As an example, I bought my TREZOR at the end of 2016, at a price of 0.1361 BTC, which is now a whopping $1000. This has got to be one of the most expensive TREZORs ever owned.
In a way, this is Laszlo's pizza story, in a much, much smaller scale.
Moral of the story:
HoDL!Spending bitcoins just makes it so that converting my salary to bitcoins is no big deal.
If I were buying something on Amazon with fiat, I could have just as easily bought bitcoins with that fiat.
But by spending bitcoins I get a 15% discount. Plus all of that time between getting paid and spending my bitcoins my currency has gained value instead of lost value.
Of course that's true, I'm not saying you shouldn't do it. After all, it's good to use BTC in everyday life. All I'm saying is that calculating the current value of the BTC we've spent on things may leave a bittersweet taste in our mouths...
