This unusual asset is actually a mineable token meant to mimic Bitcoin but built on the Ethereum blockchain. This asset was mostly created as a protest to the fact that basically all tokens on the Ethereum chain must be purchased instead of mined like cryptocurrencies were originally.
To that end, the creators of this asset wanted to make a token that could be mined, like Bitcoin, but would also have all the features inherent with Ethereum's own chain. This allows for a more fair distribution of assets. While the goal is admirable, it's unlikely that many projects would make the switch to a mineable ecosystem. ICOs are just too profitable.
If you are planning to make a 0xBitcoin investment, then you should know that the use case for the token itself is iffy. However, since this is an ERC20 token, that means it can interact with any existing services of this nature, and that gives it a little bit of built-in adoption so to speak.
There is also one other interesting scenario involving Ethereum. Once the Ethereum network goes proof of stake, there will be no way to mine it. Users will however still be able to mine this token, and that might actually give it a very interesting place with small-scale miners.
Investors can buy 0xBitcoin on only a few of the lower volume exchanges. This strange crypto does have a surprisingly large trading volume for what it is, and investors should be able to easily execute a trade. Trades can also be completed using two different trading pairs. Investors are free to utilize either Bitcoin or Etheruem for the swap, as both of them have decent liquidity.
This is an ERC20 cryptocurrency, and investors looking for a safe place to store their investment will need to seek out an Ethereum based wallet. There's a ton of ways to do this, and if you be sure to choose a safe wallet, then you'll be okay. If you need some help, then you could look into the Meta Mask plugin or possibly an Android or iOS wallet such as Coinomi if you'd prefer an option that can store multiple currencies in one easy to use application. No matter what wallet you use, take the time to create a backup of your seed on a sheet of paper in the event that your device becomes inoperable.
