if you had invest in bitcoin, would you follow the price every couple hours? if you had a job you would be more focus on your job than whats on the screen of your phone. you would be fired from your job? maybe. investing in bitcoin is hard on you everyday at every time. it can fall down to 1000$ in 2 hours if you dont pay attention to it. if you wanted to sell before that big dip but you cant because you are at work. invest what you can afford to lose. investing in bitcoin for a person working an 8 hour job is something else. i think thats why the price havent risen lately because people are more worried about their job than investing in a volatile market.
I have better solution for workers. Bitcoin is not the only one cryptocurrency but it is the savest one for investment. There are many type of cryptocurrency, one of them is called masternode coin. It can provide you passive income, actually you will not be able to avoid market impact to your investment but Masternode coin will give you more coin which will reduce bad impact of market. Fortunately I have found XCPO, the XCPOs' team have good project to keep their coin alive.
