@OP is looking for temporary solution, it's better to hold in hot wallet, but make sure @OP can control his finger to not clicking random link/download/install something.
I know that. But if it is a really huge amount, i still wouldn't advise anyone to hodl it in a hot wallet, even if it is for a short time, let alone on an exchange. "Huge amount" is relative, but anything greater than $10k on a hot wallet even for a short time is too risky IMO. It would make more sense to even set up an airgapped wallet, that is if OP has an old device and the knowledge to do it, and use it for the meantime, until his hardware wallet arrives. Maybe i am just too paranoid, but that's my advice.
