This is a decentralized application that allows users to store and update all of their relevant information in one place. Unfortunately, this is one of those blockchain projects that just does not really seem to need a token. While it may be useful to have all of your information universally stored, there are many applications that do this for free already, and without the need of a token.
When choosing an investment you should always ask yourself first whether there is a need for a product, and then whether that product is the best one for the job, and it's hard to win that argument in this case.
This service has however gained a large number of followers, and they have one feature which could save them. The ability for users to better control their personal information. Unlike the other services mentioned before, your Dock investment will actually allow you to control who accesses what data.
Now the only issue is getting other services to actually use this process, which will be tough as they will be reluctant to give up unrestricted access to their current user's data. There is a use case as a launchpad for other decentralized applications, but it seems unlikely that companies would use this service over Ethereum, which this product is actually built upon. Investors are encouraged to research the project thoroughly before making any investments.
It's possible to buy Dock on only a few exchanges, but they do have some high-quality listings. Several of their partners have very high trading volume, and that's good news if you're interested in putting some money here. Bitcoin is the highest value trading pair available, but there's also plenty of room in the USDT and ETH trading pairs to make a trade.
This is an ERC20 token. Interested parties will need to find a safe Ethereum wallet to store their tokens in safely. This is easily done as there is a wide variety of wallets which cater to these assets. A few great choices for this include Meta Mask, My Ether Wallet, Coinomi, and JAXX. Fortunately, when it comes to ERC20 tokens, no matter what device you have access to, there's likely a wallet available for it. This makes them very convenient for investors. You should, however, be sure to take steps to protect your funds at all times. This includes making a backup of your recovery phrase and being very careful about the sites you visit, as there are many scams out there that will try to steal your passwords.
