This coin project was a fork of Ethereum. The developers of this project split from the original chain in an effort to manage the project the way that they chose. Unfortunately, this leaves EXP as a less desirable version of Ethereum. While they have instituted some interesting features, such as allowing the project to earn a small portion of income from any DAO smart contracts that are processed.
This essentially allows them to be self-funded, without the need for any additional money to further development and marketing. The innovation seems to end here, however, and if you make an Expanse investment you should know that they don't have very much going for them other than being a clone of another coin.
They do however offer investors some rewards for holding, and there is a "grant" available for developers interested in creating applications on their chain. Unfortunately, it's unlikely that software developers would want to launch their app on Expanse when they could do it on the much more popular Ethereum chain and reap the benefits of their many advancements that are about to happen.
Investors can buy Expanse on only a small number of exchanges, but they do have some very good listings to their credit. The trading volume is pretty good, but there is unfortunately only one trading pair available. Investors will have no choice but to use Bitcoin if they want to make a swap. The liquidity is however pretty evenly distributed between their exchange partners, and this makes it easy to purchase your coins on the platform of your choosing.
In order to store your investment safely, you'll need to download the official wallet application from the project's website. The developers have made available installation packaged for Windows, Mac and Linux operating systems. After downloading and installing the appropriate wallet, make sure to make a backup of your wallet file in a safe place. This will be required if you ever need to restore your wallet on another machine.
