Syscoin entering the year 2018 will be more popular, they are very solid from the team and the community until until now they become one of the options for holding.
Although we are growing, we aren't a new team by any means, Syscoin has been around sins 2014; I'm one of the co-founders (but not the leader, that's Dan Wasyluk, Blockchain Foundry Inc CEO and he has managed the Syscoin team since the start; he's also the OP of this thread- Danosphere).
What have we worked on? Syscoin, Blockmarket, Syscoin API, Releasing 3 microsoft Azure products and much, much more that is currently under NDA and cannot yet be discussed.
Our team is also comprised of several developers that have many years of software development experience.
