So I have a nooby question since I am not a miner:

Lets assume I start minning with the Obelisk SC1 Miner today. Will the difficulty be the same. I would make about $15-$20 per day with the Obelisk SC1 at the Moment, right?
So baiscally when the Obelisk SC1 is shipped in June, it will be totally useless - basically a waste of Money, right?
