From the title of the topic you write, I could guess that you are new in the bitcoin market and a new investor, yet that's too soon to say how 2023 will be because most of us don't even have any information about what's going to happen even in a few weeks and until today just 10 days passed from the year of 2023, so we cannot say anything about it yet. but from what we saw during these years depending on how you aim every year can be profitable for investing on bitcoin if you are aiming for the long term.
I am not ready to invest for a long time right now. Currently I have some money with which I trade to make some more money and then prepare to buy and hold bitcoins for the long term. I think buying bitcoins at present is definitely profitable but I need to be patient enough. But I don't have that much patience right now so I want to invest in Altcoin with a small amount first. And later invest some profit from here in Bitcoin for long time.
