As the title says, is passive earning from Bitcoin is possible nowadays. Let's face the facts mining is very much expensive for most of the users and I have encountered with many people who think they do not have any skill or do not want to learn any soon. There must be anyway by which you can make money by using most of your time by investing only once or by a little investment.
Mining is really a way of earning a passive income and most of the people who's engage to this system are maybe really rich people that has the ability to support what are needed in doing it. Most probably the main factor why other investor are not going to this system it's because of lack of investment or capital because of the very expensive machine that are using in mining and also the cost of it's consumption of electricity. Otherwise,in trading, this is also has an investment but not expensive as mining. You can invest how much you can afford but this is a very risky method. There's a possible chance of losses.
I do not think that mining is the passive income from Bitcoin. You have to invest in equipment and take care of it. You need to pay for the electricity. Holding BTC can bring you an income, but you have to wait for awhile.
