Thank you, I already know this website but I'd like to know how to calculate it so I can quickly calculate the quantity of a certain currency without starting to mine and looking at the amount of coins that I would mine in a day.
Calculator posted in this website is easier one, If you want to calculate manually then you first of all need to know the difficulty of the coin which you are going to mine and the real time exchange price block reward and block reward timing so you can get how much you are going to gain.
