BTC 1h updateSince 9 PM on December 11, the 1-hour chart shows an uptrend, with support levels forming at 99,587 and 100,309. A double-bar spring appears to be developing at the 100,309 support, with the first bar showing a notable volume spike and the second bar still forming. If this spring completes and confirms, the price could rise toward the next resistance level. After the spring, the 5-minute chart may offer a good entry point for a long position.
