Don't worry. You're the not the only one who has lost so much for holding alts instead of bitcoin! This hard fork in my opinion should generally help the ecosystem but alts might continue to suffer as long as bitcoin continues to dominate the space. If you want my advice, don't give up on something you believe in. If you believe in steem, average down your costs by buying more cheap. If you don't, you can either write it off and hope you're wrong or take the 0.07 BTC now before you lose even more!
