The balance of interest rates than the current life is much higher, but put in to work ineffective. The bitcoin is up and down, the risk is too great. Which is more suitable for investment?
It really depends on what needs to be seen in the investment. There's nothing that is going to make one choice or the other the best since you can be investing just to keep the money safe or you can be investing in something to hopefully see the investment grow. There's a lot of different things a college student might be taking into account in a situation like this, and in most cases just making sure that you have your money safe is the superior choice for a college student since they can't afford any losses to their wealth. As such, making the profit might be good if the student is able to lose the money and doesn't need it dearly in the future, a literal interpretation of the "only invest what you can afford to lose" adage.
Mind explaining your situation a bit more so we can offer a more detailed explanation instead of the general comments we can really provide?
