The best explanation to them is by telling them that cryptos are also real money in the sense of digital. While there is digital money that are coming from e-wallets nowadays and even e-banking.

Crypto is the same, but it's not the fiat money that we use to transfer from those platforms. Women that think crypto is a scam, they're not wrong because some projects are also scams but they are generalizing it which is wrong.

Trust me, if you're able to make some conversion and give that money to them from any altcoin that you own or bitcoin that has been sold, they'd easily believe.
