I'm already invested in BTC for the long term. I'll just Hold for now.
I'd buy more if I could, with the prices going down.
It probably won't go lower then 3000$ USD
I read a fascinating article today mentioning a Goldman Sachs guy who predicted BTC hitting a 4800 USD exactly, and then correcting back to 2000-2300 range. So far ALL of his predictions came true, so I will personally try to stick to his forecast and try to buy in as much as I can at the 2000 range which I hope would be the bottom.
Oh, and the guy also predicted that after this correction, BTC will skyrocket in space
