The Swiss national train service making Bitcoin purchases available through all its ticket machines means a lot. Breaking 7000 isn't inconceivable next year with mainstream companies like that taking Bitcoin seriously. Bitcoin's all over the news again, and for the right reasons. The news of the Bitfinex hack held the price down, but once good news started again the price started breaking upwards.
PS
The OP ihas a typo in it, "Consifering" should be spelt considering.
700 Seems big, but so did 1000 back in 2013. However, I doubt we'd jump that high in 2017. Bitcoin is gaining more tracking and the growth may be exponential, but I'd expect to see a fall and a quiet January before it jumps again. Pure speculation though.
A lot of people consider that an ATH over the next few months is a done deal. All we need is something to get the bull rally started off.
We know how insanely prices can be pushed up in the crypto-world.
