IMO Factom is the biggest sleeper of all, reminds me of Ripple around this time last year. Spending time on the Ripple forum when the market cap was 200million was a trip. All the information and deals were there but the floodgates were not open yet. Factom is a long established coin too and doing much of the same. Insane amount of development and making deals left and right all covered by NDA's however once the Genie is out we can expect a similar catapult in the price.
Last year around this time Factom was #9 on coin market cap and there were points in 2015 where it was top 5, before the ICO boom factom was very much on the radar of a lot of investors.
Big name investors have been involved, Tim Draper being one (bought us marshals auction of silk road btc).
Its an important year for factom with m3 coming, lets hope everything goes well
