Without hesitation I would pick bitcoin for one simple reason. Banks can freeze my account and money, but with bitcoin no one can freeze your coins.
I do not think that it is good you put all your money into bitcoin because of possible risks that this task has.
One should never put all their money in any kind of investment. Best is to have at least 50% of your money in your savings account, and the rest you can use to invest in something. That allows you to earn a certain amount of profit throughout the year. You just have to make sure that your money is growing.
