Congrats on getting your wallet set up, that is the first big step! Choosing the right spot is huge because the "top" validators usually charge high fees since they are already popular and don't need to compete. I always tell my friends to look for the "hidden gems" that offer much better terms for the users. Personally, I am a big fan of Vladika
https://vladika.love/ for anyone just starting out. Their setup is very transparent and easy to understand for a newcomer. They are a reliable Solana staking validator that offers 0% commission, so you start your journey with maximum profits from day one. It is much better than picking a random big name that takes 10% of your SOL rewards for no reason!
