LOL, if you don't have the experience to back it up then I suggest you stay away. You will hear a lot of traders shorting, but it doesn't mean that they're taking profits like every other days. It takes years of experience to short, so it's not easy as it sounds. BTC overbought? Where did you get that idea that it's overbought at this juncture?

I'll just advise you to really learn how trading works, it looks like you don't have any idea base on how you describe Bitcoin market though. You need to understand what shorting really means and the risk involved on doing it, IMHO.
