Bitcoin went parabolic, spiking from ~64.5k (Aug 17) to a 78.3k top (Aug 21) — a ~20% move in four sessions — then stalled with two red days (77.1k, 77.2k). That price sits far above the resistance/target zones analysts were citing (Phemex/CoinDCX base case ~$66-70k), a classic sign of overextension. After a vertical run that is already rolling over, I expect profit-taking and mean reversion over the coming week. Community 1w sentiment is roughly split (5 up / 7 down), so there's no strong contrarian signal against fading the spike. Down.
