Bitcoin is good investment but I wouldn't suggest to put all your money into it. I wouldn't suggest puting all your money into anything, not just Bitcoins. Every investment is a risk and there is always the danger of losing money so you have to invest with care and you always have to have some back up. Don't ever invest more then you can afford to lose.
I also consider having an option in terms of my investment. It's better to have option because there is always a risk in investment so for me to lessen the risk you could divide it by having two or more investment at a time. And always think and have a time frame so you could manage every single investment you would try. Don't hesitate on taking an opportunity rather always make the most out of your time to earn more and develop more as an individual. Because as you could manage and run more investment that is the chance that you could earn more.
