This is a masternode coin that provides its users with instant, private and secure payment transactions. While it doesn't really offer much that's different from any of the other options out there, it does, however, plan to designate 10% of its rewards to the common good. However, the developers do not go into much detail about what those charitable causes will be.
If you're interested in making a Pura investment, then you'll likely be interested in running a masternode which can earn you a decent return every month. You'll need to acquire 10,000 coins minimum if this is the case, and you'll also need to learn how to set up the node using your own VPS. Interested parties should take this into consideration before making a purchase here, as it does take a bit of know how to get this set up running.How to buy?
It's only possible for you to buy Pura on a handful of exchanges, but the trading volume here is substantial enough that it should be easy to complete a trade without any issues. Bitcoin is really the only useful trading pair here, even though there is also a pairing for Ethereum. The later does not seem to have enough liquidity to support trades readily, so you'll be better off sticking with Bitcoin.
In order to store your coins, you'll need to consult the official website for the appropriate wallet download. There is a client wallet download available for Windows, Mac, and Linux operating systems. After selecting and downloading the correct package from Github, don't forget to encrypt your wallet with a strong password and create a backup of the wallet file someplace where you will not ever lose access to it. If you ever need to restore your funds you'll need this.
