Cube is creating a product to cater to a threat that does not yet exist, but it likely will very soon. Self-driving vehicles are currently being tested in major cities all over the world, and it's probably not too far off that consumers will have them as well.
Your Cube investment is essentially betting on the fact that others will try to take advantage of this interconnected vehicle network. It's a pretty good bet. If there's a computer system out there, then someone will try to compromise it.
That's not all though, they also plan to be a data hub for drivers. Motorists will be able to record and then monetize the data from simply driving around. This is a potential goldmine for the automotive industry who will likely pay to have information such as this.
It's possible in the future that privacy protection laws will prevent them from harvesting this themselves, and it will be necessary for them to ask for permission using a service such as this.
This relatively obscure asset is available on only a couple of exchanges. You may need to make some alternative accounts if you are looking to buy Cube. However, there is a good volume for both Bitcoin and Ethereum, so it should be easy to make an exchange using either of these digital currencies.
This is an Etherum based asset. That means you can safely keep your tokens in any wallet that allows for the storage of ERC20 tokens. While there are many good choices here the most popular is often My Ether Wallet. If you'd prefer a non-web wallet then you can also look to mobile apps or a hardware wallet like Trezor for storage options.
