Bitcoin has just erased part of its rebound after a peak at 82281 dollars on September 4. Indeed, the price dropped back to around 79000 dollars, a decline of nearly 4% in a few hours. The daily trend remains favorable, but short-term indicators signal a loss of momentum. It is the maintenance of the support located around 78500 dollars that will now determine whether this decline remains temporary or invalidates the recent bullish breakout.
