The cryptocurrency market experienced a decline for the second consecutive day on Tuesday, with both bitcoin and ether losing approximately 0.75% since midnight UTC. This downturn follows two unsuccessful attempts by bitcoin to breach the $80,000 resistance level over the past week, the most recent of which occurred during Asian trading hours on Monday. The enthusiasm from last week's surge from $70,000 to $79,500 is beginning to dissipate as several key price indicators turn bearish, including the Coinbase Premium index, which has flipped negative, signaling waning demand from US investors.

US equities are poised to open lower on Tuesday, with Nasdaq 100 futures trading 0.5% lower since midnight UTC, while the US dollar index is up 0.25%. The stalled peace negotiations between Iran and the US continue to influence traditional markets, with Brent crude oil now firmly above $105 per barrel. The positioning of derivatives and other market trends also warrant attention.
