As far as I see it Bitcoin BTC will go up in price, drasticly after it proved itself to the world that it can withstand any attack. That the Core developers are on the right track, as good things do take time.
The effect of Schnorr signatures will be one of the proofs of code that will pump the BTC price very fast. And the further acception of SegWit by businesses as Bitpay and Coinbase, early 2018, will even push the price of Bitcoin BTC to much higher levels.
My expectation for Bitcoin BTC will be that it will rise to about 50.000 USD, before a 20-30% correction will occur, after which it will climb again. Same goes for many other real Cryptos, like Litecoin, Steem, Bitshares and also cheap ones like Dogecoin.
It will be when the total market cap has passed 1.5 trillion in USD, somewhere in the fist quarter of 2018.
This is a personal prediction and it is purely build on my own speculations.
