I think Decred will do amazing this year, and is well deserving of that. Other value speculations aside, I believe this will be the year of private and zero-knowledge coins, we've seen it with BTCP (which I think is a complete trash fork for many to dump for gains). Lightning protocols are being integrated into multiple coins and is definitely something to keep an eye on IMO. And lastly, the ASIC business was already out of hand but now it's just ridiculous with Bitmain's announcement of an Equihash ASIC.
