About 6 million coins are added/year right now (about 11% inflation rate), but anything that's being staked gets the lot of these coins. So with less than 1/3 of the total coins staked at this time, you get more than 33% a year. The more coins that get staked the lower the rewards/staked coin will be.

There's been a huge amount of announcements, and great developments for GoChain in the last month.

-They've secured a large company to run two of their nodes (DISH Network) and build tools on GoChain. In order for GoChain to reach it's own goal of decentralization, they'll need 49 more company such as this in different parts of the world to run their nodes. The network runs as intended already though, but not to the degree of decentralization that they hpe to achieve. DISH build on the GoChain most likely relates to a planned expansion into 5G.
-There's several other companies that are looking at GoChain and as such could be candidates to run nodes/be building on GoChain. Travis CTO of GoChain has become advisor to Salesforce. Microsoft has launched a proof of concept regarding Decentralized Identity on the Blockchain. Redcat is looking at running drone tracking on the blockchain and have GoChain as a major candidate.
-GoChain as an ICO platform has had a slow start with few realizations. But there's now a planned exchange called Pukkamex that intends to be the first to run an ICO on GoChain. If successful, it may be interesting to see what happens when GO becomes a major asset of an exchange, even if it'd be a small and new one, it may have some success as it looks as if it might be marketed towards Arabic investors in particular.
-Most interesting of all, however is that the platform itself is evolving. GoChain is already a top performing blockchain. The most prominent features is that it's ETH compatible, so that anyone who is running an app on Ethereum can choose to upgrade to GoChain in a couple of seconds. Therefore anyone building on Ethereum, is potentially switching to GoChain in the future as long as GoChain can continue to outperfom EThereum as a platform. Further, since it has a very practical approach to the consesus mechanism (with only 50 nodes that don't need to perform "work"), it's very fast, very scalable and very energy efficient (important for big companies looking to reduce their carbon footprint). That's all old news though and something many might wonder (even after they realize how good GoChain is) is whether GoChain is a big enough "brand" once the competition catches up and improves their chains to compete. But GoChain just recently developed something completely new. Upgradable Smart Contracts. That's an edge that might take some time for competing chains to implement. It's a real development that will make building on the blockchain easier and above all, less risky.

While all this has been revealed the price has been dropping like a stone. I think the future ahead may be bright though.
