Analysts note that derivatives market indicators continue to show continued bullish sentiment for Bitcoin as the weekly, monthly, and quarterly options expiration date for Bitcoin approaches this Friday (June 28). "Call options far outnumber put options, especially above $65,000," said Bartosz Lipinski, CEO of Cube.Exchange. "This is likely a byproduct of the bullish sentiment we had earlier this month, rather than the current situation we are considering - German authorities have sold Bitcoin heavily, spot Bitcoin ETFs saw outflows of about $900 million last week, and are down sharply from recent highs," Bitfinex analysts also pointed out the bullish-put option bias, highlighting that the put-to-call ratio for the quarterly options expiring at the end of June is 0.53.
