I have heard and also read in various threads that mining is too risky. The invested money can all be gone with a blink of eye. Actually i am not sure wither i should do it or not. If i invest, then is there any chance to loss all the money?
If i invest, then what should be the amount first?
And in which sites would be better to do mining?
Well if it is cloud mining that we are talking about, there is actually a very high chance that you'll lose all your money . I'll suggest you to make a final decision for the better, whether to invest to it or not . It'll be better for you to Try to learn any other ventures instead .
