Monero relies on cryptography to audit the supply, and to make sure only you can spend Monero that you own.
Bitcoin doesn't rely on cryptography to audit the supply, but it does to make sure only you can spend Bitcoin that you own.
Both monies rely on mathematical cryptographic assumptions to work. Monero relies on more significant assumptions.
It doesn't make logical sense to discount Monero entirely as money because it relies on cryptography. Both rely on cryptography, Monero just relies on it more heavily.
