Cryptocurrency usage in wealthy countries is mostly investment. Usage as money – for saving, sending and spending – concentrates in places where the conventional system serves people badly.
Where it is
Countries with high inflation, where holding local currency means watching savings evaporate and holding dollars is restricted or impossible. A stablecoin is a dollar account nobody can freeze.
Countries where remittances are a large share of income and the conventional channels charge a substantial percentage and take days.
Countries where the banking system excludes large parts of the population, and a phone with a wallet is the first financial account someone has had.
What it looks like
Stablecoins, overwhelmingly. Volatile assets are not useful as money and the people using crypto as money know that better than anyone.
Peer-to-peer trading through messaging apps and informal networks, because regulated exchanges are unavailable or untrusted.
Merchants accepting it directly, particularly for larger purchases where the alternative is carrying cash.
The risks users face
Scams, which target exactly this population. Loss of keys with no recovery. Regulatory crackdowns that arrive suddenly. And the same volatility everyone faces, if they hold anything other than stablecoins.
Why this matters for the sector
Because it is the use case the technology was built for and it is working, in places most commentary ignores. The narrative in rich countries is about price. The narrative where adoption is highest is about function.
What would change it
Better local banking, which would remove the need. Or regulatory hostility severe enough to make it impractical. Neither is imminent in the places where usage is highest.
