Block.io provides zero fee transactions for users, developers, and merchants.However, we do not deal in money.Block.io (as of October 5th, 2014) uses MultiSig addresses that require two signatures for every withdrawal/transaction: yours, and Block.io's.This means that Block.io has no control over your coins, and cannot move your coins without your signatures.This also means that in the event that Block.io is compromised, none of your coins can be lost because of just that event.MultiSig addresses exponentially increase users' wallet security.If a sending wallet/service says the MultiSig addresses at Block.io are invalid, this means the sending service does not support MultiSig addresses.It is very likely that the service is insecure, and outdated.We recommend you stop using that site or service immediately, and contact the developer for comment.When you signed up, we asked you to save your Secret Mnemonic.Do you have this?If yes, go to Settings, enter the Secret Mnemonic (ignore the Secret PIN field), and then your new Secret PIN, confirm your new Secret PIN, and click 'Change Secret PIN.'

Similar to the more established bitcoin, it has already promoted the product to its current client base.The company therefore claims it has 131,176 registered businesses ready to use LEOCoin, potentially making it the "second largest digital currency" in the world.Its own exchange LEOxChange will kick into life on April 2 but the coin will also be recognized by existing exchanges.Read MoreWhy the world's banks should stop shunning bitcoin "This industry (so far) has been like the Wild West," Dan Andersson, the co-founder of LEOcoin said at an event Wednesday morning, which took place at the Tower of London.His colleague and co-founder Atif Kamran called digital currencies the "evolution of money" and extolled its benefits for the e-commerce community.The more popular bitcoin is a "virtual" currency that allows users to exchange online credits for goods and services.While there is no central bank that issues them, bitcoins can be created online by using a computer to complete difficult tasks, a process known as mining.

The cryptocurrency has sparked interest among venture capitalists on both sides of the Atlantic but has also run into regulatory issues in many countries.Currency analysts have also warned of its unstable nature and the Bank of England has also provided reach of the hypothetical risks that it poses to financial system.LEOCoin boasts that its currency based on newer technology than its rival but Andersson admits that the two will essentially co-exist.He also said that it would have greater usability and accessibility than other cryptocurrencies.It provides instant transactions and no commission fee on purchases, according to the press release, although sales will be subject to a transaction fee., and are also lower than more established payment systems like Western Union and Paypal.A number of so-called "altcoins," or alternative coins, have sprung up alongside bitcoin.Jon Matonis, a founding director of the Bitcoin Foundation, an organization aimed at promoting the cryptocurrency, is lukewarm on the addition of a new "altcoin", telling CNBC via email that there are too many of them.
