Bitcoin drops 4.3% to below $88k as crypto selloff deepens

Bitcoin dropped as much as 4.3% to below US$88,000 on December 1 in early Asia trading, while ether fell 6% to under US$2,900, according to Bloomberg data.

The declines follow a weeks-long cryptocurrency selloff that started in early October after US$19 billion in leveraged positions were liquidated, shortly after Bitcoin hit a record high of US$126,251.

Bitcoin briefly rebounded to above US$90,000 last week before the latest downturn.

Sean McNulty, APAC derivatives trading lead at FalconX, said the biggest concern is weak inflows into Bitcoin ETFs and limited buying during price dips, and he expects structural headwinds to continue this month.

McNulty said the next key support level for Bitcoin is US$80,000.

The selloff comes ahead of US economic data releases this week, which could impact expectations for Federal Reserve interest rate policy.

🧠 Food for thought

Implications, context, and why it matters.

Weak ETF inflows lack hard numbers, which masks whether demand is fading

  • The piece cites weak inflows into Bitcoin Exchange-Traded Funds (ETFs) without numbers 1. IBIT drew $32.8 billion after its options launch and now holds 57.5% of bitcoin ETF assets, up from 49% in Oct 2024 1.
  • A daily or weekly net flow split by fund is missing 2. Without it, readers cannot tell if outflows sit in GBTC or across funds. IBIT’s growing share hints at rotation, not disappearance 1.
  • The claim of limited dip buying lacks context. U.S. Form 13F filings are quarterly disclosures by institutional investors. They reveal active hedging and shorting with longs 1. IBIT put activity clustered near the $60 to $62 strikes in late Oct 2025 3.

Volatility is driving hedging demand for simple BTC ETF options tools

  • Bitcoin fell 4.3%, and near term IBIT implied volatility stood at 42% on Oct 30, 2025 3. Retail and institutional holders face drawdown risk. Many bought near $126,251.
  • Platforms can add one click protective puts or covered calls on spot Bitcoin ETFs. Start with IBIT, which has about 40 cents of options open interest per dollar of bitcoin held 1. Fidelity’s FBTC sits near $1.3 billion in options open interest, about 25 times smaller than IBIT 1.
  • IBIT options activity rivals Deribit, a major crypto options exchange 1. Deribit’s daily options volume typically runs between $4 and $5 billion 1. Liquidity supports market making and cuts execution risk for retail platforms that automate hedging without deep derivatives know-how.
