Asked and answered many many times. Storj always pays out the USD value and calculates the Storj amount at the moment of payout. Please treat people who are trying to answer your question with respect. @kevink wouldn’t state it with such certainty if he wasn’t sure.
The reason is simple, Storj Labs doesn’t want to enforce people to take on token market risks. USD is stable so paying out in that is the most fair. If you still want to profit from the market risk, feel free to buy tokens! If they held your payout in tokens you would be forced to take on the market risk and there is nothing you can do about it. Which may be fine right now, but would definitely lead to a lot more (and more reasonable) complaints if the value drops.
