Odaily Planet Daily News Analysts pointed out that as Bitcoin's weekly, monthly and quarterly options expiration date approaches this Friday (June 28), derivatives market indicators continue to show continued bullish sentiment on Bitcoin. Cube.Exchange CEO Bartosz Lipinski said, "The number of call options far exceeds the number of put options, especially above $65,000. This may be a byproduct of our bullish sentiment at the beginning of the month, rather than the current situation we are considering-German authorities sold a large amount of Bitcoin, and the spot Bitcoin ETF saw an outflow of about $900 million last week, and fell sharply from recent highs. "Bitfinex analysts also pointed out the bullish-put option bias, emphasizing that the put option to call option ratio for the quarterly options that will expire at the end of June is 0.53. (TheBlock)
