I think that's when Bitcoin no longer plunges to strong support of $ 7k for a long time. This is a very good signal that the bulls are very strong in pushing prices above $ 7k and hope this will sustain.
If this is sustained, it will lead to a new trend, we can expect the price of bitcoin to rise to $ 20k again. I'm not kidding, once bitcoin is created a new trend and the psychology of people who have been waiting for long will be willing to buy bitcoin at a high price because many people expect the price of bitcoin to rise.
