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.
Even though bitcoin could offer people an opportunity to earn. It is not a good thing to go all in a specific investment. It could be better if you would have an option for you to have an opportunity to earn more and to have a partial profit on every type or way you would take to earn bitcoin
