#btc This morning, the BTC whale launched another surprise attack, creating a historic new high of 108366 and quickly dumping to crash, triggering the main downtrend of the 4️⃣h, causing continuous declines throughout the day, and dragging down various altcoins of Ethereum! BTC hit a low of 103066 in the afternoon; I believe this position is a valid support because there is strong support below (purple area in the image)! Therefore, it is very likely that this main downtrend of 4️⃣h has temporarily released! Pay attention to the upper resistance level 1️⃣105101 and resistance level 2️⃣105728!
