Bitcoin has surpassed the threshold of 91k USD (if you are talking about the price in VND or USD) and continues its upward trend, this is a very positive sign in the current market context. If you predict that BTC will not be strongly corrected to 76-77k USD (or equivalent), this may be based on factors such as cash flow into the market, investor sentiment, or supportive macroeconomic factors.

However, it should be noted that the cryptocurrency market is always highly volatile and deep corrections can still occur even in an upward trend. Risk management and closely monitoring signals are very important. If you have a long-term investment strategy, don't forget to regularly update information from reliable sources.
