Why domain expired, but not purchasable?

Looks like it's expired at 03/14/25.

Why from domain trading sites, I found it's not sellable?

Do I need to wait?

Yes you will need to wait, there usually is a 30-45 days grace period, the original owners can still renew the domain in this period.

You might need a drop-catching service to secure the domain if it's deemed valuable.

thanks!

thank you so much
