It is my personal belief that in the longrun, BTC will continue to rise.
But like you said: you're a short term investor... I personally don't think there's any way to predict what BTC will do in the short term, so in my opinion, you took an educated guess, and i really hope it pays off for you.
The great thing about BTC is it is both for long term and short term investment. Everyone know about long term but for short term, you can buy at 970$ supoose and then you may sell at above 1000$. If you are looking for short term profit, just wait for few days and hope price will be down again to buy below 1000$.
