5. People for whom fiat money is impractical for one or more reasons

This category is way larger than people in well-banked Western circles realise. Bitcoin (crypto) is one of the easiest ways for people affected by capital controls or sanctions (on the financial institutions they use, or the country they were unlucky enough to be born in) to freely move their (legally earned, and taxed) money across borders.

Since one of the countries with strict capital controls is China, and one of the countries affected by sanctions is Russia, the scale of this usage of crypto is huge.

All these categories are like about 5% each, the 80% is normal hard working people who don't like hard working — it is literally hard work! — and to whom crypto gives hope as a magic box in which one throws pennies and dollars come back. It's a bit creepy (the game is in fact zero/negative sum) but then gambling is not generally illegal.

This is a false dichotomy with 4 choices instead.

1. Bitcoin users who hate the fractional reserve model of banking with fiat or the ability for the Fed to print fiat arbitrarily is probably a majority

2. Hold Bitcoin for illegal uses, probably a small minority as there are better options such as Monero for illegal uses

3. Probably a majority of Bitcoiners are opportunistic investors. Why is that bad?

4. Web3ers, a minority of Bitcoiners. You are thinking of altcoins. (Yes Ordinals on Bitcoin are now a thing and are controversial in the Bitcoin community, but most Bitcoiners are hard money proponents who are not interested in NFTs)

internationally, 2 using cypto for illegal or unofficial means to transfer money is definitely more than 90%. The rest can share the remaining 10%.

Category 1 was probably predominant during the early days of Bitcoin, so the old hands probably still hold onto to that notion.

point 4 is pretty much 3.1
