Bitcoin once again tested 80K, but the real battle is just beginning. 👀 For $BTC, the 80K–82K range is not ordinary resistance. - About ~8% of the BTC supply was acquired in this zone. - The average cost for ETF investors is also around 80K–82K. - The 50-week MA is near 81.1K. - Spot Bitcoin ETFs have seen net inflows for 8 straight days, totaling roughly $2.8 billion in that time. On one side there is strong institutional demand, and on the other a massive supply wall. Even more, there is about $6.4 billion worth of BTC options expiring this Friday. For me, the critical zone is very clear: Holding above 80K–82K: a strong confirmation for the rally to continue. Below 77.5K–78K: the first important signal that short-term momentum is weakening. 🟢 My daily directional expectation: Today, my main expectation is sideways to slightly positive, but I remain cautious while price is below 80K.
