My teenage child has been mining crypto overnight when he's not otherwise using his computer, approximately $1500 worth in 2021. We file separately for them with the form 8615. I've added the crypto mining as hobby income via Schedule 1, line 8. Does the IRS currently consider such mined crypto as "earned" or "unearned" for the purposes of the 8615. If it's "earned" can he contribute to a Roth IRA?
