In my opinion , Volatility won't be a concern when using stablecoin for payment , but for other altcoin, it can be an issue . The value of a coin could change between accepting a job and receiving payment . in the worst-case scenario the coin could become worthless turning you into an volunteer . Overall there are more pros like low fees and near instant withdrawals .
That's why there are stable coins so that it won't be hit by volatility. But the thing is if the value of USD changes compared to your local currency then there's still the volatility in there but that's another thing to be concerned of. As long as you're going to receive it then there's no problem at all and then let yourself do all of the worries in there.
Other payment methods , like Paypal can take 1-3 days to transfer to my bank account .
And this I think why they're improving their services and trying to make it as real time deposits.
