Possible scenario if we stay in the 2017 channel for bit longer.
But that would be underestimating the insane fomo that can happen. Segwit, LN, they are all gearing towards a compelling bull-story.
I think it would be too soon to retest and break ATH after only 2 months, but you never know. There's a lot of institutional money waiting to get in as infrastructure is being facilitated by Coinbase, Gemini, and now Poloniex.
Another route this could take is that exchanges will enable direct FIAT-Altcoin pairings. That would hurt BTC marketdominance and give us a alt season without precedents this year. Probably the last time to make plenty of BTC before it goes to the stratosphere through mainstream adoption.
