In the summer of 2016, the Cosmos whitepaper was released. In the spring of 2017, the Cosmos fundraiser was completed. In the first months of 2019, the software is feature complete. The launch of the Cosmos Hub draws near. What does this mean for Atom holders?
If you are an Atom holder, you will be able to delegate Atoms to validators on the main network and vote on governance proposals. In fact, the future success of the network depends on you responsibly doing so! However, you will not be able to transfer Atoms yet. Transfers will be disabled at the protocol level until a hard-fork is executed to enable them.
