Hi @andreolf I think most likely Bitcoin won't fork, especially because of bip91, but will still see a drastic drop in marketcap before aug1 because of doubt and unclearness around this whole event.
Both BTC and ETH will shoot right up in the days past aug 1. in my opinion.
but these are just guesses and theories, no one know what's going to happen.
