Banks and government authorities are anticipating bail-ins, steeply negative interest rates and hefty fees on cash, and they want to close any opening regular depositors might have to escape these forms of officially sanctioned theft. The escape mechanism from bail-ins and fees on cash deposits is physical cash, and hence the sudden flurry of calls to eliminate cash as a relic of a bygone age.
The benefits to banks and governments by eliminating cash are self-evident:
Protect from inflation - No withdrawal restriction - Very low transfert fee.
Mobile payments made easy
Bitcoin on mobiles allows you to pay with a simple two step scan-and-pay. No need to sign up, swipe your card, type a PIN, or sign anything. All you need to receive Bitcoin payments is to display the QR code in your Bitcoin wallet app and let your friend scan your mobile, or touch the two phones together (using NFC radio technology).
Security and control over your money
Bitcoin transactions are secured by military grade cryptography. Nobody can charge you money or make a payment on your behalf. So long as you take the required steps to protect your wallet, Bitcoin can give you control over your money and a strong level of protection against many types of fraud.
Just like with email, you don't need to ask your family to use the same software or the same service providers. Just let them stick to their own favorites. No problem there; they are all compatible as they use the same open technology. The Bitcoin network never sleeps, even on holidays!
Fast international payments
Sending bitcoins across borders is as easy as sending them across the street. There are no banks to make you wait three business days, no extra fees for making an international transfer, and no special limitations on the minimum or maximum amount you can send.
Choose your own fees
There is no fee to receive bitcoins, and many wallets let you control how large a fee to pay when spending. Most wallets have reasonable default fees, and higher fees can encourage faster confirmation of your transactions. Fees are unrelated to the amount transferred, so it's possible to send 100,000 bitcoins for the same fee it costs to send 1 bitcoin.
Protect your identity
With Bitcoin, there is no credit card number that some malicious actor can collect in order to impersonate you. In fact, it is even possible to send a payment without revealing your identity, almost just like with physical money. You should however take note that some effort can be required to protect your privacy.
In the history of Bitcoin, there has never been an attack on the blockchain that resulted in stolen money from a confirmed output. Neither has there ever been a reported theft resulting directly from a vulnerability in the original Bitcoin client, or a vulnerability in the protocol. Bitcoin is secured by standard cryptographic functions. These functions have been peer reviewed by cryptography experts and are considered unlikely to be breakable in the foreseeable future. It is safe to say that the currency itself has never been 'hacked'. However, several major websites using the currency have been hacked, often resulting in high profile Bitcoin heists. These heists are misreported in some media as hacks on Bitcoin itself. An analogy: Just because someone stole US dollars from a supermarket till, doesn’t mean that the US dollar as a currency has been 'hacked'. Most bitcoin thefts are the result of inadequate wallet security. In response to the wave of thefts in 2011 and 2012, the community has developed risk-mitigating measures. As these measures gain adoption by merchants and users, the number of thefts drop.
Using a hardware wallet is the most secure way to store your money. They keep your bitcoins in an offline storage and when connected to a computer, they enable a highly secure way of spending as well (immune to viruses, hackers and keyloggers).
