I don't know why you choose to sell your laptop to invest in Bitcoin, but the question is do you have other gadget, if you have they is fine, because it will definitely pay later for longtime investment.

For the remaining money, I think is best to focus DCA to invest more rather than saving it in the bank. Thos will help you add value to your portfolio, note money save in the bank is not a portfolio rather a liability either to the bank or you.
