High volatility can be good for options buyers as it increases the likelihood that options will be 'in the money' (profitable) at some point before expiration, thus creating profits for buyers. 'As BTC continues to struggle below $100,000, we could also see altcoins starting to catch up again,' QCP stated, adding that a month ago a similar trend was observed when Bitcoin traded at current price levels.
