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.
If what you want to do is to multiply your bitcoin, there are not many ways to do this, you could invest in the bankroll of bitcoin casinos and obtain a cut out of the profits, but now many casinos are creating their own tokens and they are paying dividends to the holders of those tokens so this could be another option if that is what you're looking for.
