So far, there is no evidence that SpaceX has sold its cryptocurrency assets on the market, but there was definitely a panic in the market.
Maximum fear in the market will be present when bitcoin drops to $8,000-$9,000. At this point most retail traders are likely to lose faith in crypto and sell the entire spot in order to earn some money. At this time large investors will continue to buy up the asset as they still believe in the future behind the blockchain.
