i think i have a premium misspelled domain name and i have some questions about copyright

about a year ago i have bought a misspeled domain name of instagram it the same like instagram only the last letter is changed and the the domain name loke like common word/vocabulary typos it got some traffic daily, and i never use it for getting any profit i only installed a simple wordpress theme witout any content and tracked his traffic with google analytics,
i have some questions about the domain :
can i sell it to instagram ?
will instagram sue me ?
can i sell it to anybody else ?
