Out of all the terms used by the Bitcoin community, this is the one that grinds my gears the most (most other I think are pretty good). The Bitcoin ecosystem is a technological marvel, seeing what people can build using both the base and the LN layer is amazing, seeing a decentralized monetary system actually work as well as it does is magical, and a lot of the catch phrases used by Bitcoiners are meant to educate people - Not Your Keys, Not Your Coins; Don't Trust, Verify; Bitcoin, not Blockchain...
Why do I say all of this? Well, the term in question - Have Fun Staying Poor - does none of the things mentioned above. It's very derivative of a fiat mindset. Sure, it's cool that we get rewarded for being pioneers in the economic revolution that is taking place in the form of Bitcoin becoming more valuable as time goes on, but that's not the point of this and it never was. Bitcoin isn't an economic investment, it's a philosophy/technology investment, terms like HFSP don't give that idea and it's more akin to the shitcoin market than the Bitcoin market. I wish we could get rid of it entirely.
There's a point that can be made about HFSP being about fiat becoming less valuable, and not Bitcoin becoming more valuable (for being freedom money), but that's clearly not the intent behind people who use it, the intent is about number go up, unfortunately.
Anyways, this was just a thought I had the other day and I thought it'd be a fun exercise to start a discussion about it :)
