The main owner of Bluesky helped create a social media platform that discourages bots and hate speech and lets users curate their feed as they wish.

You can leave your Twitter account in place—and you may want to, if there are particular accounts you want to follow that aren’t on Bluesky. Keeping your account also prevents anyone from taking your username (and maybe pretending to be you). You will need to log into your account periodically so your account isn’t deemed inactive.
