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!
