The value of your cryptocurrency can indeed fluctuate while you’re gambling. Most crypto casinos handle this in one of two ways:
They convert your deposit to a fiat currency equivalent (like USD) for gameplay, then convert back to crypto upon withdrawal.
They keep your balance in cryptocurrency, which means the real-world value of your balance can change.
In either case, it’s important to be aware of potential value changes and consider using stablecoins if you’re concerned about volatility.
