Since the world didn't have enough crypto currencies, somebody thought to create yet another one, this time in a perplexing manner. To put it shortly: he implemented the Bitcoin characteristics in an Ethereum smart contract (deployed, obviously, on Ethereum). It's called [0xbitcoin](https://github.com/0xbitcoin/0xbitcoin-token/blob/master/README.md) and it's basically an ERC20 token, but based on the Bitcoin Core characteristics: * No pre-mine * No ICO * 21,000,000 tokens total * Difficulty target auto-adjusts with PoW hashrate * Rewards decrease as more tokens are minted So, instead of creating an ICO and then having people sending ETH to get the ERC20 token, this contract dispense the 0xbitcoin tokens based on a small CPU miner (downloadable at the same link above). You get your own Bitcoin, on top of Ethereum :) I don't know if somebody deployed the contract yet, but it's nice - and mind-boggling, obviously - to see such a technical feast. *** _I'm a serial entrepreneur, blogger and ultrarunner.

Wanna know when you're getting paid?

I know the feeling. That's why I created steem.supply, an easy to use and accurate tool for calculating your Steemit rewards

It's free to use, but if you think this is a useful addition, I'd appreciate your witness vote.

Thank you!
