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.
