For Dogecoin price movements, this will look good, but for Elon Musk who has this product when receiving Dogecoin payments, he must be prepared for the risk that when making transactions using Dogecoin the price collapses and will only make him lose, so he must accept that risk.
Your explanation is quite reasonable, maybe Elon Musk is afraid of losing large amounts of money, but for now we can buy accessories owned by Tesla by making payments using dogecoin.
There is no business executive whose orientation is to lose money, so Elon has thought about the best way possible for his company to make transactions with Doge.
Certainly, those that are not very vital and affect the profits that can be achieved. X is likely to be able to receive payment in dog but he doesn't know when that will happen. he will definitely see the movements of the doge too, so that it doesn't make him lose money.
Maybe when the next bullish season comes, he will dare to do it. We are waiting for his actions.
