This is sort of a side project from the already popular blockchain startup Game Credits. While it's not really clear why they need a separate token for this, it will be used for competitive play. These kinds of activities are collectively known as "esports", and it's where players go head to head online in various video games for prizes.
This is already a pretty huge industry, but the idea behind this application is that it will bring this kind of functionality to more casual players. In the past, these types of tournaments were really only something that PC or console gamers would participate in, but now, with ever-growing mobile gaming market, there's an entirely new player base which can be marketed to.
It's very likely that applications like this which allow people to earn cryptocurrency rather than buy it will be the tipping point which pushes casual users into the blockchain camp. However, it should be noted that while your MobileGo investment does have a rather limited supply, it likely won't be a great token for acquiring value.
Since most of this project's user base will be casual players simply trying to earn money, it's likely that they will immediately cash out these tokens. They have no real incentive to keep them, and this downward pressure will be forever dropping the price of your investment. While some price appreciation is possible, it's something to keep in mind.How to buy?
Investors can buy MobileGo on a wide variety of exchanges. That makes it extremely convenient to invest in this particular token. There's also a good deal of liquidity here, and you should have no problem executing a trade quickly and for a good price. Seeing as the trading volume is spread out nicely between the exchanges and pairings, you should also be able to choose where you'd like to trade without any complaints on pricing. Investors can take advantage of several pairings including BTC, ETH, and USDT.
This is what is known as an ERC20 token. That means you'll need to find a compatible Ethereum wallet if you want to safely store your investment. Fortunately, there's a ton of options for this, and it's easy to find one of these. ERC20 is the most popular token distribution protocol, and many wallet creators cater to these assets. Once you find a wallet, make sure that you protect it, and that you never give out sensitive information to anyone such as the recovery phrase, as they will be able to steal your tokens using this.
