We've been expecting the burn for a few weeks now, or depending on your trust in the overall quarterly burn schedule, it's been foreseeable for years. Recently BNB price has increased drastically, so it's difficult to say how much boost can still be expected from burns. But in general burns should increase the price of the remaining supply.

Other effects, which might easily make more difference, is the psychology of the burn. It grabs attention for the currency already ranked #3 in the market by cap, and the native currency to the largest exchange by far.

Previous ATH was ~$637, and another run usually makes coins spike up at least near previous ATH. If it manages to break ~$635, the next big hurdle will be $650. If that is broken, there's a free path to $700 imo.

All of this is more or less well founded speculation, so please don't make any decisions based off of it. But that's what I'm thinking. I should also mention that my portfolio is heavy on BNB, so I'm also biased in that regard.
