Can someone who understands finance explain what this means in layman’s terms? How is it just saying they sold Bitcoin so they could have cash on hand?
Having $XM USD in BTC means nothing if you can't convert it back into USD. This sell (at least according to Elon) was done just to prove to Tesla/Board/etc/whatever that it was fine to hold BTC because they could convert back to USD if needed at any time.
that is to say, I don't think tesla had any worries that someone wasn't ready to take the other side of their ask, very likely the round trip was already arranged from the day they agreed to take a billion in BTC onto their balance sheet. if elon can 'prove' the market has liquidity, everyone backing Bitcoin wins big, Tesla included.
Tesla simply sold just enough BTC to book enough profit to meet quarterly EPS estimates.
