Started investing in bitcoin - maybe it is still not too late

After seeing all time high and a pretty big fallback in the past days, I’ve decided to get in it. Made 4 purcases mosly at ~112k and one at a bit above 113k. It’s not much, in Hungary, this is the beet I can do right now. Today I made enough money to finance my gasoline consumption for one whole month, I consider this as an achievement, since I’ve never tried crypto before. No, I don’t plan to sell BTC to finance my car’s fuel consumption!???? I want to hold it for at least a few months or end of the year. Dou you have any tips to a beginner in BTC investment? Dou you usually have any other type of cripcurrency besides BTC and whet?
