Ironically, the number of people who use Bitcoin directly (that is, on the blockchain with their own address) is significantly smaller.
Most people use Bitcoin via exchanges, where they keep the coins. The average crypto user from Nigeria has zero interest in paying $10+ transaction fees every time they need to do anything with their money.
At this point, it doesn't matter if they own BTC or ETH or DOGE or whatever. They just want whatever allows them to move money around. The exchanges could simply keep balances in a database and reconcile them amongst each other via contracts, and it wouldn't make any difference as far as the end users are concerned (There are examples of this happening between exchanges).
