Congrats on your first buy I still remember when I bought my first Bitcoin on a local exchange for fear of losing money but I still gave up everything I bought my first coin and from that year till today I am still stuck with Bitcoin & crypto market.
The biggest lesson I have learned in crypto is to store your coins in a wallet where you take ownership, of your keys, and your coins. Hence I suggest going with a Hardware wallet or paper wallet for better protection. Also, distribute your coins to different wallets.
