Europe is experiencing a severe energy shortage this winter so I wouldn't be surprised when they enact this ban. Currently, many companies and businesses in Europe are on the verge of bankruptcy because of energy shortages as well as too expensive costs. This ban is likely to be temporary and it will be reinstated when the European economy recovers and things return to normal. This will definitely affect the bitcoin price but won't be too severe as we all know the root cause of this ban, IMO.
