stackhat

An overly cool 1980's-1990's helmet made by Rosebank in Australia. Popular colours included fluoro yellow and green, white, and dusty pink. Parents were known to draw eyes on the back of the helmet to ward off the deadly 'magpie dive'.

#stacksats

A Bitcoin (BTC) is composed of 100 million smaller units called Satoshi’s or sats. “Stacking Sats” is the process of buying these Bitcoin components and saving them as they increase in value over time.

I got paid on Friday and bought 1 million sats for $81. I will continue to #stacksats until I am wealthy enough to buy a house for myself.
