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?
I think if you invest in mining you will not lose the things that you exploit. You only lose money to maintain, repair mining equipment. Exploiting more and more means that the device is easily broken
If the difficulty rose too fast, you may not get back the original BTC invested to buy the miners. That is the lesson I learned.
