According to @GreeksLive, on August 15, 39,000 BTC options expired with a Put-Call Ratio of 0.95, a max pain point at $118,000, and $4.6 billion in notional, while 280,000 ETH options expired with a Put-Call Ratio of 1.04, a max pain point at $4,000, and $1.3 billion in notional, source: @GreeksLive.

Key strike references flagged for monitoring are $118,000 for BTC and $4,000 for ETH as the stated max pain levels, source: @GreeksLive.
