This project is yet another cryptocurrency exchange/wallet combo targeted at the mobile market. They allow investors to buy and sell their cryptocurrencies using a convenient mobile app. They also plan to offer their users a Mastercard branded payment card which will allow them to convert cryptocurrencies to their native currency on the fly when shopping with merchants, or to get cash from ATMs.
There will also be a Change marketplace which will allow for the users of this application to invest in P2P loans, real estate or other investments, but there does not seem to be any other details about this available yet.
Unfortunately for CAG, none of these things are actually ready yet except for the mobile app, and they may be too little too late. There are already options available that are working for users that need a cryptocurrency debit card, and they have a very big competitor about to release a killer product right next door.
If you plan to make a Change investment, then you should make sure that you research all of their competitors thoroughly before you make any investment decisions.How to buy?
The list of exchanges upon which can buy Change is pretty small. The trading volume also seems to have greatly suffered, and investors should be cautious here. Low volume assets could possibly be delisted from their exchanges, and it can make it difficult to find a buyer if you need to offload your tokens for any reason. This token does, however, have multiple trading pairs available, and you will be able to make an exchange using Bitcoin or Ethereum pretty easily.
This is an Ethereum based token. These types of tokens are known as ERC20 tokens, and you'll need an Ethereum based wallet such as Meta Mask in order to store them safely. There's many other options for this if you'd prefer a mobile option or even a hardware wallet. If this is the case look into Coinomi for mobile devices or Ledger if you'd like a safer hardware wallet option. This project is actually a wallet itself as well, so you could store your tokens there too. No matter what wallet you choose, make sure to create a backup in a safe place.
