You're kidding right?  Their sale set off the liquidations of Celsius, Three Arrows Capital, Luna, along with several other major players.  Even the mention that Tesla sold 75% of their holdings caused a further 136 million dollars in liquidations.  Tesla actually performed God's work here, making sure that when prices do rise, it isn't the degenerate gamblers with tons of leverage that get rich, it's the people that stayed the course and stacked sats in their own wallets.  That's why people are talking about it.  It was a big deal.
