Bitcoin is currently in a good trend, so prices will continue to rise steadily, if traders don't sell their bitcoin and there is no bad news coming for BItcoin, I am optimistic that the price of Bitcoin is very good at the moment.
traders are always selling their bitcoins, that is why they are called traders not investors. basically trading means constantly buying and selling assets to make profit from their ups and downs. the reason why price goes higher is because more investors are coming in and increase the demand which in turn takes the price higher.
I agree with the rest though, we are already in a upward movement and the start of the next bull run to the next much bigger ATH and if we see no "bad news" this trend will continue with only small corrections on the way.
