You mean which validator to choose?
There's several criteria to select a good validator. This includes the commission they take, their uptime, their support (is it easy to be in contact with them?) etc. The APY is the same for every validator. We have a dedicated channel for all things staking where you will find lots of information, can ask questions about staking and there are also validators advertising, feel free to join it: https://t.me/casperblockchainstaking
Thanks, i will join to know about.
An other question, how to become a validator?
You will need to have a bid in the top 100 validators. You can read about it here: https://docs.casperlabs.io/operators/ https://docs.casperlabs.io/glossary/A/#auction You can find the validator auction here: https://cspr.live/validators-auction
