I ran the tool, chose Segwit and lo and behold my BTG were there!

This was acknowledged by the Open Bitcoin Privacy Project , ranking Airbitz in the top 3 wallets of Airbitz is one of the few wallets on the market that offers true financial autonomy.
This is important because the purpose of bitcoin is to give control back to users. You may have used two-factor authentication before when making bank transfers. Usually, it involves receiving an SMS with a code to prove you are using a certain device.
Airbitz includes this extra security layer without needing to type any SMS codes or do anything extra. Transactions are always encrypted before being sent out or saved to your phone. This keeps you safe from attackers, malware, and even the Airbitz servers. What I find cool is that the app will boost your level of encryption on more powerful devices. So a balance of speed and security will be found for you.

For developers, the software is open source, meaning you can extend the platform with your own apps. You can learn more about that here. Glossary Best of Bitcoin. Mike used MultiBit, which was popular at the time but has since been discontinued due to numerous flaws. It's obvious MultiBit was written in a hurry: The interface is counterintuitive, presenting you with a prominent button that says "create wallet" that allows you to generate new wallets inside the software.
Most users only need one wallet, but MultiBit practically demands that you set up multiple. On top of this, it allows you to add multiple passwords to each wallet, even though these aren't required. With only a few minutes of clicking, you could create dozens of wallets, each with dozens of passwords.
In short, it has a lot of room for error. In March , on an unseasonably sweaty night in Hong Kong, Mike created a new wallet on Multibit, moved his 40 bitcoins into it and then added a password.
In the infinite wisdom of the MultiBit programmers, there was no option to double-confirm the password. Hope you typed it in right! The problem was, Mike knew he hadn't.
He tried what he thought was the password, and it was rejected. Again and again he was bounced. His finger had slipped when he entered the password, he was sure of it -- there was an extra keystroke somewhere. But which key, and where? Since Mike was in the bitcoin game for the long haul, he moved on after a week or two of trying and retrying his password.
He figured that there would be a solution one day, and so he put his MacBook with his MulitBit wallet in a safe corner of his office, where it quietly died from a motherboard failure. Mike called me earlier this year.
He spoke like he was in a confessional, cowed with shame and begging for forgiveness. He told me he was planning to fly to the offices of KeepKey, the new owners of the legacy MultiBit products, and I told him to wait. As I listened to his problem, I got it into my head that I could fix this for him, even though I wasn't sure how. I knew a fair bit about how bitcoin wallets work, but I was certainly no expert. In short, it was worth a shot. Getting the hard drive from his old MacBook would be easy, just a matter of plugging the drive into a new computer.
The challenge was the MultiBit side of things. I tracked down an old version of the now discontinued software and discovered that there were multiple ways to restore wallets using MultiBit. The software generates encrypted backups for each wallet, and it also encrypts separate backups of the private keys.
The entire program and all wallets inside of it could also be restored from the seed words, but Mike had, of course, lost those too. It soon became clear that we had, at best, a 50 percent chance of success: We could either decrypt a wallet backup or a key backup.
To do either, we'd have to use a password that Mike would have to remember. I broke the news to him, and he offered to pay me a percentage of whatever we could recover. Although I could try to restore his wallet remotely, he wanted me to come and sit there with him. This was as much a personal failure as an IT failure, and he needed someone to share the experience with. This is the full moon festival, celebrating the fall solstice.
In Hong Kong, this means several days of public holiday. First things first, we had a technician from one of Hong Kong's bustling computer malls transfer the data off the dead hard drive -- we got him on his last day before the holiday.
Retrieving the data was an easy enough operation. Soon, we were looking at the MultiBit backup files on my computer: So far, so good. It's helpful here to understand what a bitcoin actually is.
The best explanation I've heard is metaphorical: Money began as a physical object, and then it shifted to become your identity i. But cryptocurrencies like bitcoin are virtual objects, which means they exist in the digital space, not tied to anyone's identity.
Like a digital dollar bill, a bitcoin can be traded, stolen or lost. But this is still just a symbolic representation of the actual fact: A bitcoin is really just a cryptographically locked address on the blockchain, so rather than having a bitcoin "on" your computer, what you actually have is the private key that can unlock a bitcoin's location on the blockchain.
It was that key that we were searching for in Mike's mess of MultiBit folders. Now that we had the backup files, it was time to get to unlocking. Mike had seemingly created half a dozen or so different wallets when he was securing his bitcoins -- no doubt, a result of the software's baffling interface. The good ol' process of elimination would narrow this down to the wallet that was the ultimate destination for the bitcoin. We loaded up the first wallet file and entered the password Mike had intended to type all of those years ago, and it unlocked.
That was a good sign: It meant we knew the password Mike remembered actually worked with at least some wallets -- just not, perhaps, the only one that mattered. The wallet started syncing to the blockchain. The blockchain is often described as a decentralized public ledger. In practical terms, that means it's a long list of every transaction that has ever occurred.
It's "decentralized" because every transaction is confirmed via a math problem solved by computers set up as "miners. The full moon was rising in Hong Kong, and we ate Thai food, anxiously waiting for the blockchain to sync.
We watched as the wallet displayed 40 bitcoins arriving on Nov. It also displayed the current value: This looked like success, but I urged caution: The chain was still four years behind present day. At some point it stopped being tragic and started becoming darkly comical. At 1 AM, we checked another wallet.
This time, March 20th, , passed, and the coins remained. We waited an agonizing additional half hour for the blockchain to finish syncing, and We had found what we were looking for. All that was left was to transfer the coins out of this mess and into a modern wallet we decided on using Exodus, which is easy to use, simple and secure. But the transfer asked for another password. Remember, MultiBit lets you add additional passwords to wallets. This is what Mike had done on that sweaty night back in We tried the password we knew, and We tried again and again, carefully calling out each character as we entered it.
We had found ourselves on the bad side of the fifty-fifty. Why does MultiBit encourage you to use multiple passwords? Why doesn't it at least ask you to confirm your password before saving it?
