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.
You are probably mistaking "investing" in bitcoin for trading. You can buy bitcoin and just hodl them, for example. It have a decent annual appreciation which is usually well above the inflation rate in most country.
Besides if you're trading you can just check the exchange on your phone if you really want to be always updated. If you're trading btc for alts, you can also set buy and sell orders, most exchanges have that function. You don't have to be staring at the chart 24/7.
