He's twisting interpretation to justify his BTC investment, and make it NOT look like the punt it is. One can be pretty sure that he got the long BTC at a deep discount (25-35%), and used some of the 'saving' to hedge it with with put options and futures. As long as the asset (BTC) is volatile, and MTM settlement is guaranteed, he does well. The why he's in BTC.
The inflation rant is an exaggeration. CPI is the best measure we have, and it is easy to adjust - the rich man's basket of goods is also very different to the poor man's. If you day-trade all day, including changes in the value of your assets AND your liabilities is valid, but you aren't main street. CPI is a measure of MAIN STREET inflation, not rich man inflation.
At 4B invested, the 30% liquidity discount is roughly 1.7B. Deduct 100M to set up option/futures hedges, and even a monkey should well. Smart investment; but it really says that a big player in the BTC space is trying to get out, and is trying to create liquidity events to do it. BTC didn't just run up to 19K/BTC by itself!
30%? Typical collateralization requirements on stable-coin are 130-150%.
More collateral for a larger exchange, stop-loss starts at a higher collateralization rate. MORE volatility.
Good for everyone
