I/O Coin is a digital currency released in early July of 2014.After the initial mining period "Proof Of Work" phase there were approximately 16 million coins minted.Just like any currency (Dollar, Euro) I/O Coin has a real world value.This value is based on the latest trades on digital currency exchanges.You also earn interest on the coins you hold in your wallet, by allowing them to 'stake', Staking helps secure the network.In turn, users are rewarded with a small unit of a coin for the length of time the wallet is open and staking.We have a highly skilled team of developers, who have created our own Proof of Stake system 'PoS I/O, HTML5 wallets, DIONS decentralized usernames allowing to send coins easily via a registered username and Android Mobile wallet with a Point of Sale feature, not seen with any other digital currency.How to buy I/O Coin?We are one of the most developed and feature rich digital currencies.We focus on long term innovation.The world has just been introduced to digital currencies and many still do not know about Bitcoin, which has had a lot of media attention.

Just think of digital currency like an internet connection in 1992.Most people knew about the internet and only a few used it with a 56k modem.Large adoption came a few years later.The technology was there and evolved quickly just like the state of digital currency today.Digital currency is just like that.Once people begin to realize and understand what a big advancement digital currency is, allowing people to pay for goods and services easily and quickly, with much less fees for merchants, mass adoption will soon follow.Our Team is prepared for that.I/OCoin digital currency is developing a digital coin that will make an ideal payment system, with a strong blockchain technology to future proof our development.I/OCoin has been at the front of pushing the boundaries of what can be achieved with a digital currency.We have introduced IONS (soon to be upgraded) which is a fantastic feature that allows you to send and receive payments by simply using a pre-registered username, E.g.Johndoe.io, making it very easy for anyone, anywhere to send and receive I/OCoins.

Not only that, but we are the first to develop a true stand alone, HTML5 desktop wallet.This was a great challenge to the team, but once again goes to show the dedication and talents we have.Many alt coins tried to make a HTML5 wallet and all had failed, this includes coins such as Litecoin, Dogecoin and Peercoin.Our new HTML5 Wallet features a super user friendly, secure and slick interface, that departs from the old bitcoin qt wallet.The I/O Coin team packed eye catching wallet skins that are easily interchangeable adding 3 different color schemes.The wallets feature AES-256-CBC to encrypt the private keys that are held in a wallet.With a slick interface, fast transitions and integrated IONS section, making it easy to send I/O Coins to friends and family using our aliases to send to username.In the future our wallet will expand to support new technologies in crypto.Mobile wallet that allows you to send i/o digital currency and receive by simply using a registered IONS user name!No longer do people have to worry about remembering long wallet addresses.

All you need to know is the user name of the person you wish to send the coins to and not only that, if you are unsure of the name, you can easily open the IONS address book and quickly find the name and send the number of coins.bitcoin physiqueIt really is that easy.cara mendapatkan bitcoin mudahOur wallet also features a Point of Sale mode.bitcoin mining tutorial ubuntuYou can now easily create invoices and has the ability to share via app, email, bluetooth or text message.bitcoin mining hash calculatorAuto conversion between currencies and a barcode scanner, are also new added features for easy pay at any I/O Coin accepting Merchant.bitcoin-qt portable

In this post I’ll explain how I’d recommend storing and handling bitcoins.Don’t take my recommendation for granted, I’m also learning and can make mistakes and will change my opinion later.Do not trust anyone and think twice (and then think twice again) before doing anything.The rule is to split, diversify and brace for impact.Make yourself comfortable with an idea that your money will be stolen.Not a matter of “if”, but “when” and “how much”.You can only limit the damage, not to avoid it completely.Looking for a perfect solution leads to denial and irrational behavior.You should understand the layers of security and how they reduce, but not eliminate the risk.You should also understand how to split your money in independent parts.When you purchase some BTC on an exchange and keep them there, you are fully trusting the exchange operator.If they get hacked or simply steal your coins, you will have a very hard time recovering them (chances are almost zero).Also, attacks are more probable where the payoff is the biggest.

People will continue attacking wallet services and exchanges because it is where the most of money is concentrated.When you purchase some BTC, you should move most of them out of the exchange to a private wallet immediately.You may keep some amount on the exchange in case you’d want to sell quickly (beware of panic sells when someone runs a DDoS attack) or in case your main wallet is lost or stolen.Some people sell at some unusually high price moving it a little bit down, and then organize a huge DDoS attack on exchanges and popular Bitcoin websites.This creates panic in newcomers who suspect that the bubble is going to blow up and they give up their money to those who know better.I myself have no experience, nor desire to play on price changes, so I don’t recommend at all trying to play this game.Invest only the money you can lose and save it for a long run.Maybe, if it gets 10x more than you invested, you can sell back 10% to cover your expenses and then be a relaxed spectator without risking a heart attack.

This is never-done-before technology, no one knows what price is fair, opinions differ from $0 to $1000000.It can go quickly up, then quickly down.Or be stable for a while before unexpected jump or drop.If you are in for a long run, temporary changes do not matter.If Bitcoin succeeds, it will be big and shiny.If it fails, it will fail so quickly, you will not be there to dump it.Just accept the wild swings and limit your investments in the first place.Your personal computer should be secure.Without viruses, trojans, keyloggers, corporate monitoring software, add-ons, kernel extensions etc. My recommendation: do not use Windows at all.Buy yourself a modern MacBook Air, turn on FileVault2 to encrypt the whole disk (even if your password is weak, disk encryption reduces the risk of private keys being leaked when the system swaps RAM).Allow only Mac App Store apps and DeveloperID-signed apps (it is on by default).Never install any generic UI extensions, never enable access to assistive devices (unless you really use them yourself), never install any entertainment apps or games except Google Chrome.

Never install Flash, or Java or any other kind of runtime plugin to your browser or the whole system.Never ever install kernel extensions: sorry, VMWare and Parallels require them and I wouldn’t trust them messing with the OS kernel just to be extra safe.Install apps preferably from the Mac App Store — they can be pulled out quickly in case of a problem and most of them are sandboxed (which usually means app cannot mess with any of your files and has many other limitations).I recommend two wallet apps: “official” Bitcoin-QT and Blockchain.info.Bitcoin-QT is a so-called “full node client”.It downloads all transactions and operates without trust in any single server as advertised.It is the most maintained, most used codebase.It is also not the easiest to use as it syncs slowly, occupies gigabytes of disk space and UI is pretty ugly.Bitcoin-QT encrypts private keys with a passphrase (by default it doesn’t, you have to turn this on).To use it safely, you need to have a good passphrase and regularly backup the wallet in several safe locations.

On OS X the wallet is located in ~/Application Support/Bitcoin/wallet.dat (all other files, especially blocks folder should be ignored by your backup program).Split your coins in two or more wallets.Bitcoin-QT does not allow you to easily switch between them: you need to shut it down, rename one of your wallets in wallet.dat, start Bitcoin-QT again.Use different passphrases for each wallet.Store them in different locations.Remember: whenever you do something with your wallet, or move money to another one, always keep all backups and first try with smaller amounts.In case you accidentally send to a wrong address, you better have some older backup with the keys.When the new update of Bitcoin-QT comes out, download the new version from the official website, verify its checksum and keep it on disk for a while.If in a couple or more days there were no reports of a hack on a download server, launch the app, but for a good measure do not enter your passphrase for a bit more.Blockchain.info is a web service that allows navigating Bitcoin blockchain and provides an online wallet.

The wallet is stored encrypted on the server and decrypted only on client side (in JS in your browser or in iOS app “Blockchain”).As always, if you forget the passphrase, you will not be able to access your funds.Other apps support importing wallet backup (like MultiBit), so you won’t fully depend on their server to do your transactions.Blockchain.info is still a 3rd party service and one day may steal or leak your wallet password (e.g.if some hackers sneak in and place a honeypot), so do not trust more than 10% of your funds.I recommend enabling 2-factor authentication via e-mail code (SMS code is also possible, but is less reliable) - in order to sign in on the web site, you would need your alias (username), e-mail code and a password.Also install the iOS/Android app and protect the whole phone with a passcode.If you e-mail authentication stops working, or your e-mail account is stolen, you’ll still be able to make payments from the phone.Also, copy a wallet backup somewhere outside your mailbox (they have some integration with Dropbox, maybe you should try it).If your funds get really expensive, you may try a good old paper.

I’m far from that happy day and haven’t tried this myself yet, it’s only my current thoughts that might be helpful to somebody.Paper wallet is a private key which was create on a secure computer, printed on a paper and wiped out from any other storage.It may be protected by a password, but usually, it’s just a raw key.It is safe from hackers, but not safe from physical access.You should keep it in a very secret place, or in a vault.There are different levels of paranoia involved in creating paper wallets: from a web service which does all work for you (but can be compromised on different levels) to a completely new, clean computer never connected to the internet, with a virtual machine where the password is generated and then the disk is burned down.Blockchain.info provides some helpful material on how to deal with paper wallets: https://blockchain.info/wallet/paper-tutorialPaper key has one important aspect: when importing it to a wallet and sending a portion of money, make sure where the change goes.

If it goes back to the different address, your paper key may become useless as your money is now on some new address created by your wallet app.Be very careful not to delete the wallet before you make sure where the funds actually are.Some people already lost quite a lot of money because of careless manipulation with paper keys and deleting the wrong thing too early.When you try a new application, or a service, or a piece of paper, or a backup, always start with small amounts and see if you can get it back and forth smoothly.Try the whole cycle, enter your pass phrases ten or more times, so it gets boring.Then, wait a week and try again.If it works, and you did not forget where your stuff is stored, how it is encrypted and if it still accessible, then add a bit more funds there.Never put yourself in a situation where you risk half or more of your funds while pressing buttons.Do it in small portions and check each portion that it has arrived where needed and that it is still accessible.Conclusion: be extra careful, double check everything, play with small amounts first and remember the rule: split, diversify and brace for impact.
