that link you give to us its show about margin trading, i think you have big budget to do margin trading because as far as i know, doing margin trading is too risky if we don't know about trading or we only have small knowledge to make analysis. but i hope you know what you are doing and i hope you can make profit too.
I also think about that. If he do margin trading, then why he could ask this simple question and make a thread just for selling. Make an analysis for an altcoin to do speculation is a must. But yeah, sell it now!
