WILL IT BE WORTH IT OR NOT HOW LONG WILL IT TAKE TO ROI?
WHY ARE YOU YELLING?
Nobody knows, everyone's just guessing. You might as well be asking what the weather will be like on October 20th. All we know is that it will be colder than it is now (difficulty will be higher). How much? It's hard to say because there are multiple manufacturers pumping out ASICs at the same time and even they don't know how many each other are delivering. Bitmain will likely release the bulk of the hashing power. I personally feel it will be worth it and very profitable - but I could be wrong.
