Don't be too optimistic about it. A 10% increase in the BTC price doesn't mean anything. Bitcoin is a volatile asset and price pumps and drops in the range of 10-20% are normal. We can't draw any conclusions about what 2023 will be for the Bitcoin traders/investors by a small price movement, that happens in January. Don't get too excited and don't trust anyone, especially centralized crypto exchanges and "crypto influencers", who are promising things, that are too good to be true.
Congrats on starting your Bitcoin journey. I also have a bunch of old stuff that I want to sell, but I can't find any buyers.

Buying BTC should not put interests first. The important thing is to enter this world and let yourself know more about Bitcoin. The most important thing is to reshape your investment thinking.
