CME Futures for BTC will Expire on 26th August 16:00 UTC.
Since mid June price has been ranging near the previous bull cycle ATH. So this can be implied as a retest of ATH by technical aspects.
Last July, we saw a price dump closer to expiry week and then a quick pump again by closure of expiry week. This august we see similar price action so far. Currently the price is above previous ATH showing some bullish nature.
