I agree that it is good moment to buy BTC, but about level of $45k in 2018 I'm not so sure. We have to remember that always after rising is correction. Now this corrections are very little, so everyone is happy. But in 2018 for sure we will see at least one huge correction, so don't be surprised guys if the price will touch $4k or even $3k later ofcourse will rise again, but $45k can be very difficult to reach in 2018.
