Digitex Futures is a commission-free cryptocurrency futures exchange with a rapid-fire one-click trading ladder and high leverage. Traders can buy and sell perpetual swap futures contracts on Bitcoin against the US Dollar and pay no transaction fees on any trades. The company will be adding extra markets such as Ethereum and Litecoin soon after the mainnet launch on April 27. Commission-free trading is made possible by using its own cryptocurrency, called the DGTX token, as the native currency of the futures exchange. Instead of covering costs by charging transaction fees on trades, Digitex meets the operational costs of running the futures exchange by creating and selling a small number of new DGTX tokens each year.
Quarkcoin is a coin which increases security by using 9 rounds of hashing from 6 different hashing algorithms - blake, bmw, grøstl, JH, keccak, skein. 3 of the hashing rounds apply a random hashing function. This compares with Bitcoin's solitary use of SHA-256 algorithm. There is no pre-mine for this coin. A new block is generated every 30 seconds and 2048 Quark is given out as reward per block at the beginning. This reward halves every 60480 blocks or roughly every 3 weeks. The initial supply of Quark is 247 million and this is expected to be mined in roughly 6 months since launch date. The supply will then continue to increase at an inflationary rate of 0.5% per year. Quarkcoin was launched on 21 July 2013.
