Can orther explain about its a good point else about the risk its to high to lose to lot on it?
I mine to keep because Bitcoin is skyrocketing and it's going to go higher in the coming years so I basically mine Altcoins and then sell them for Bitcoins and then zip my walls until further notice.
I dont know if at this stage running miners at home has becomed profitable once again, but im pretty sure yes, since the total hash is growing well on the last days. If the coin isnt one that has a good trading daily volume you should dump those, since bitcoin up and in the general altcoins will go down.
