Right now i trying to mining a lot of coins, i thinking its mabey its good to save the coins like 6-12 mdr before selling it.
Can orther explain about its a good point else about the risk its to high to lose to lot on it?
you must calculate the expenditure used for mining so that you can know your mining profits and make a decision to sell them or keep them
A lof of people here misunderstood the concept of mining, doing calculations and planning is the first thing that a possible miner should do. If he / she misses a point, there's a 101% chance it will definitely fail. Consider some other aspect first before looking at the earnings as it is only the Gross Income and not the Actual Net Income.
When you do the calculation, you also need to fact in the difficulty rise. Otherwise, there will be big miscalculaiton.
