Bad news happens a lot of time on Bitcoin Market, so this kind of announcement isn't new. Besides Tesla's announcement is somehow dumb since power energy doesn't rely on coal or fossil fuels alone. If that is one of their reason, they should stop transacting with banks since banking sector consumes a lot of energy too.
I didnt know that Tesla decided to stop accepting bitcoin, the last time I heard is they sell 10% of their bitcoin. Im late with the latest news due to my work. This might be one of the reason why bitcoin experience a correction. Anyway Tesla is a big company and their decision has an impact but the price doest rely on that, many adoption happened and there's more to look forward.
