How much segwit is supposed to accelerate transfers/sec? And how much does lightning network add? I think bitcoin is in very bad spot currently. Competition has surpassed bitcoin with their easy usage and reasonable transfer time/cost. I think bitcoin might start to decline compared to alternative coins, if these implementations wont deliver enough. These things must be delivered in a quite rapid schedule or companies will start to stop using bitcoins. Anyway this will be a very interesting year.

Ps. Don't but all of your eggs in one basket
