If 10000 people buy bitcoin at 60k per coin as an investment and later have to sell at 10k per coin to make ends meet, I somehow doubt that the guy that pocketed the difference will contribute to inflation as much as the 10000 guys trying to put up a meal for tomorrow.
It feels like saying Elon Musk will make make your next stop at the grocer's more expensive, because selling his 10% of shares for $20 billion will contribute to inflation because of all the stuff he's gonna buy with that money.
