Bitcoin below 19 000 USD 📉 Increasing volatility chance?

Bitcoin is slipping below $19,000. U.S. index contracts point to a flat opening, with a slight bearish advantage. The NASDAQ is losing after Snap's weak report and weakened sentiment around companies in the advertising sector:

• $510 million worth of options on Bitcoin expire today, supporting a scenario of elevated volatility ahead of the weekend;
• Volatility in the cryptocurrency sector has fallen recently, although the market is moderately in agreement that it will have to rise in the near term
• Sellers gain the upper hand with a drop below $19,000 and may position lower expecting a drop near June lows;
• Bulls were 'burned' by the November 13 liquidation cascade, when a weak inflation reading from the U.S. prompted the immediate liquidation of $80 million worth of bullish positions in the BTC options market

The ratio of call (call) and put (put) options pointed to 0.77 yesterday giving the advantage to the selling side.  Nearly $290 million worth of options lay on the supply side against $220 million worth of bullish options. Source: CoinGlassBitcoin, D1 interval.
