I would suspect to meet resistance around 7500 and then again at around 5500, beyond 5500 it's really just likely to be a blood bath, while there would probably be resistance around 3k like you suggested, I feel if we were to reach such a point resistance would be fairly weak.
I don't really care about BTC price. A value will go up in a long-term. Selling my altcoins pre bull run is crucial. People are panicking and trading, but not effectively. Current stats on 8000 are not promising for the day trading( BTC), but if someone is not rushing things he/her will for sure experience the profit within a year.
