Absolutely agree with your thoughts, we can not blame Elon Musk for the dropping price of bitcoin. Because in crypto market there are so many variables which can be a trigger to price drop.
I think Elon Musk one of the reason but we can use this cheap price of bitcoin to invest more on it and gain profit in the future.
I doubt anyone has ever bought a Tesla with BTC coins, especially when the bull market continues. These bitcoin payment acceptance statements were not ads for BTC, but ads for Tesla. Therefore, the rejection of BTC when paying for a car could not cause a dump, which was caused by the fact that 10k BTC was sold on the market at the same time.
