On November 10th, according to CoinDesk, today BTC broke through $79,000, with a weekly cumulative increase of 15%, reaching the highest level since February. Most of the gains have occurred since Donald Trump won the US election, and his victory has raised hopes for greater transparency in the encryption industry. The annualized rolling premium of BTC futures on CEX and CEX has pumped with the price, breaking 14% for the first time since June. CME futures basis pumped more than 10% on Friday. The rise in premium reflects a bullish bet. Traders have been buying bullish options at $80,000 since before the US election, expecting a breakthrough before the end of the year. According to Amberdata, the $80,000 level has the largest negative gamma value, so once the price reaches that level, fluctuations may increase sharply. Holding a negative gamma means that the net short exposure is maintained at a specific level. Concentration of negative gamma at $80,000 means that traders or entities responsible for providing liquidity to the order book can buy potential breakthroughs when the price breaks $80,000, thereby exacerbating the bullish market fluctuation. BlockBeats note: In trading, negative gamma refers to the decrease in the sensitivity of an investor's options position's delta to changes in the underlying asset's price. This means that when the price of the underlying asset fluctuates, a negative gamma position can increase the investor's risk, especially during volatile market fluctuations.
