It doesn't really mean anything in layman's terms. It's a transparent lie: If one were to actually take it at face value it would imply that Tesla plowed $1.5B into a "store of value" whose liquidity they were unsure of. It would make no sense. If they wanted to test liquidity they could have quietly bought and sold just the 10% position before YOLOing in the $1.5B. Tesla simply sold just enough BTC to book enough profit to meet quarterly EPS estimates.
