Let me tell you the most overused phrase on bitcointalk. "Invest what you can afford to lose" and don't buy Bitcoin only because cryptocurrencies are gaining more and more public attention. You should study the topic thoroughly and decide on your own whether or not it is worth your time, effort and money. Take your time to learn about the ways of securing coins. You don't want to lose your money because of web wallet which doesn't give you control of private keys.
