Investing with Bitcoin should not be an issue, but my concern here is that, you are holding it on a exchange wallet where you don't have fully control and if you will play long better to have a hard wallet. Second, just make sure you don't spend all your savings with Bitcoin, I know the hype of bull market is already here but its not advisable to go all in. If you are already finish with your college, then I believe you'll start to find a job that can give you a more competitive benefits which can allow you to buy more Bitcoin at your own capacity. This is as big step forward for you, and I'm happy for you.
