Bought a used truck many many years ago for $5K in btc, it would now be worth > $150K.
I've got a $1500 Instant Pot. Cooks great!
Also got a $700 PS3 game. Still playing!
Fricking purse.io.
Bought a used KNC Titan in 2016 that is long recycled now (I kept the fans and the power supply though) for 5.4
BTC.
Not my best decision in hindsight, but also not my worst
Admittedly it made me a few coins (coins that don't may be named here but are good for paying hookers according to lightfoot).
