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.
that is true. that is a very risky decision, i will suggest to put atleast half of the money in bitcoins for future needs but putting all of it is not a good idea. even in putting up a business, it needs to spare atleast half of the money to yourself.
