Decred is a hidden gem that few people know about and ever fewer understand. Founded by Company0 (the btcsuite developers who are well respected in the bitcoin space), Decred seeks to solve many of the issues the bitcoin blockchain is currently facing, such as consensus and governance.
Decred has a unique codebase, written from scratch in Golang.
Decred is a Decentralized Autonomous Organization with self funding and governance built directly into its blockchain.
Currently, Decred has a very small market cap. It was randomly added to Poloniex in early 2016 and never saw a traditional entrance pump/dump.
