Since Tesla's sale off has already happened at least weeks ago (if not months), most have understood that this news changes nothing.
It changed things when the sale materialised. The price of bitcoin was above $30,000 throughout May, and in June when Tesla sold, there was a clear drop from $30,000 to $20,000. What seems to have had little effect is the news after the fact, but the dump had a clear effect on the price drop.
