Yes, and there are many cryptocurrencies competing against each other, with security against both fraud and hacking always a major concern.
A future concern is security against quantum computing hacking their algorithms, but many say they have schemes to prevent such problems.
However, a big problem exists for using cryptocurrency for payments is the wide swings in value as an investment - it's innate variability - makes it unsuitable for many financial transactions that want to limit risk conservatively.
This is where stablecoins have real potential. DLT because it is not centralized is well suited to widespread, secure, and easy transfer via smart contracts.
I see great use of QMC's QDX quantum dots in conjunction with it's Quantum Ledger DLT to provide such systems.
