I sold my computer and bought about 0.006 bitcoin.
For the rest of money, I saved them in my bank account.
I hope this decision is right.
This is where the key is that you really understand what you are doing so that you are ready for all the risks and you will not regret it. If that's the case, I think it's the right decision to sell your computer and buy Bitcoin for investment and still save some money for your real-world needs.
What you need to do next is to be more patient and wise in making all decisions. Especially when the price of Bitcoin might fall next, so you can not panic and continue to hold Bitcoin until it matches your desired price.
