you will never find that and im sure about that. Just create your own prediction will be enough for you. People will think to share their forecast for monthly or yearly prediction but it's not for the next decade. How can you think if there was a website that was predicting the next decade? How accurate if if there's a website like that? Why don't you just create your own one like this https://bitcointalk.org/index.php?topic=5381536.0

You are asking something that people can't even answer it. doing forecast for a decade and what in the hell is this?
