The cryptocurrency market experienced its second consecutive day of decline on Tuesday, with both bitcoin and ether dropping approximately 0.75% since midnight UTC. This downturn follows bitcoin's failed attempts to surpass the $80,000 resistance level over the past week, with the most recent try occurring during Monday's Asian trading hours. As a result, the enthusiasm from last week's significant price surge from $70,000 to $79,500 is waning, with key indicators such as the Coinbase Premium index turning negative, signifying decreased demand from US investors.

Meanwhile, US equities are poised to open lower, with Nasdaq 100 futures down 0.5% and the US dollar index up 0.25%. Ongoing stalled peace negotiations between Iran and the US continue to impact traditional markets, with Brent crude oil now steadily above $105 per barrel. The current state of derivatives positioning and market sentiment also contributes to the cautious outlook among traders.
