When the first BTCs were sent and received, the developers in this case Satoshi Nakamoto, creator (or group of creators) and Hal Finney, an American cryptographer. The first version didn't last long. In fact, Bitcoin v0.1.2 was released by Nakamoto on January 11, one day before the first 50 BTCs were sent to Finney. On January 12, 2009 the first transaction was made for that Hal downloaded the first version of the client the same day of the launch, this was the first time that digital coins were exchanged in this particular case were BTC and had to use a wallet, realizing its importance.

She will play a very important role in bringing the new FaceBook coin to life.

In the same way that Satoshi Nakamoto created his own wallet that was installed on a desktop computer with Windows, the same Facebook created this wallet for everyone, but still in development you can register here to access in advance.

The cash will be digitized but for that to be possible you must simply be the one who places that money and through Calibra make the change, you can convert your local currency into Libra to add money to your wallet and vice versa if you want to extract money. To do all these conversions, the app will show your country's exchange rate so you know exactly how much money you'll get.

The reach of facebook is global and there is no doubt that more people will have greater access to the global economy. But not everything is rosy, the main objective is that Calibra is available to everyone in the world, according to their page they indicate that they are working to launch Calibra in as many countries as possible.

In this cryptographic world we must all be very aware of some fraud, but that guarantees we have with calibra, they explain that:

All accounts and transactions are verified, and the app has built-in fraud protections. Accounts are verified by official identification to ensure that you know who you are interacting with. Information from Facebook and WhatsApp accounts, if available, is also used to verify identity and prevent fraud. Calibra also has a reporting tool and dedicated customer service in the app. In the unlikely event of an unauthorized transaction, you will receive a full refund.

If you want to know more I invite you to visit the following link, Get more information about security and privacy at Calibra.

But the same happens with many wallets that even with all their security they have been violated for various reasons, one of them is by the same ignorance of the holder of the wallet and not be cautious with his key as in other very experienced cases Hacker manage to steal your keys and well you know the story of what happens.

Well despite everything there are still many doubts one of them is. Calibra will only change pound? depending on the cash of each country, that is one of many questions, I know that little by little and as this closer to the launch of the famous Libra coin and I'm sure Calibra will have the most important role as it is to handle all the money that passes through his app, I would like to know what you think of calibra, however I invite you to read the publication of a good friend @jadams2k18 that can clarify many doubts regarding wallets. Wallets. How many do you have?
