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.
So you literally sold one of your computers and not your only computer. Assuming that your story is correct, I find it strange that you ask about the feasibility of the plan after you have done it and finished, and not before that.
I will ask you a question: What if the majority here told you about the stupidity of your plan (especially if you actually sold your only computer), would you change it? Frankly, I do not imagine that, and all I can conclude is that you came to raise this topic looking for confirmation and not a real request for advice.
In general, it can always be said that it is never too late to invest in Bitcoin, no matter how small the amount is, but never forget the golden rule that says, “Never invest in what you cannot lose.”
