BTCUSD: Bitcoin Steadies Below $82,000 as ETF Flows Reverse Sharply. When Bottom?

Bitcoin steadied near $81,700 after falling more than 4.5% from Wednesday's peak above $84,800, as sharply reversing ETF demand added pressure ahead of Friday's options expiry. Spot Bitcoin ETFs recorded $635.6 million in net outflows Thursday, including $254.1 million from BlackRock's IBIT, while approximately $1.3 billion in Bitcoin options approached expiry with a reported max-pain level of $82,000. Bitcoin could face further downside toward $80,000 if buyers fail to defend support, while reclaiming $82,000 may signal an initial recovery.

Malaysian palm oil futures climbed 0.42% to 4,812 ringgit per metric ton, putting the benchmark contract on track for a third consecutive weekly gain as rival edible oils and crude oil strengthened. The contract is set for a 0.9% weekly advance, while Dalian soyoil gained 2.15% and stronger crude prices improved palm oil's appeal as a biodiesel feedstock. Continued strength in rival oils, export demand and biodiesel consumption could support further gains, although technical analysis warns of a potential retest of 4,736 ringgit support.

A decisive break below $4,000 could trigger further long liquidations, while reclaiming $4,100-$4,110 may signal improving momentum.
