Assuming it is true what you say, do you have another computer, or laptop or tablet? Because selling the computer and being left with nothing like it doesn't sound like a good idea. It is also not the same if you use it only to play games than to do work. Can you expand a bit on your situation?
Yes. I have Samsung laptop. It's a small laptop, but I think I can use it for my college life.
Well, if you have your laptop for your studies, then probably selling your computer in exchange for bitcoin is a wise idea. However, since you bought bitcoin at a higher price, then make sure to hold longer your bitcoin so you can sell in the future at a much higher price, which means selling in profits. Just increase your bitcoin portfolio through DCA, that is if you have spare money to buy bitcoin.
Bitcoin is a high risked asset, so always invest at an amount you can afford to lose. Don't invest all in, most especially that you are still a student, having no stable source of income that will sustain your investment.
