Bitcoin price hit an 11-day high, rising above $85,000. Bitcoin was relatively stable amid highly volatile markets last week. The rise came amid lower tensions and a recovery in key stock indices. The price area of $87000-89000 may represent local resistance.During the current shortened week, in addition to the tariff topic, the markets' attention will be focused on the key rate decision from the ECB, as well as, the data on retail sales in the United States and the speech of Fed Chairman Jerome Powell. Data from the United States will have an impact on the volatility of the U.S. dollar and may affect the bitcoin market dynamics.
