Then how have 140M people adopted Bitcoin?
My assumption is they include people who "own" Bitcoin on an exchange, just like people who "own stock" are counted, even though their broker holds them.
If people claim that they deposited USDT and bought WBTC or something else (On different chains, Binance chain, for example), Do you think it should be counted?
There's Bitcoin, and there's scammers trying to sell their own made-up token as Bitcoin. So no, I don't count them. They're meaningless.
