The paper that first introduced #Bitcoin
#Bitcoin payments are irreversible
A #Bitcoin transaction cannot be reversed, it can only be refunded by the person receiving the funds. This means you should take care to do business with people and organizations you know and trust, or who have an established reputation. For their part, businesses need to keep track of the payment requests they are displaying to their customers. #Bitcoin can detect typos and usually won't let you send money to an invalid address by mistake, but it's best to have controls in place for additional safety and redundancy. Additional services might exist in the future to provide more choice and protection for both businesses and consumers.
Securing your wallet
Like in real life, your wallet must be secured. #Bitcoin makes it possible to transfer value anywhere in a very easy way and it allows you to be in control of your money. Such great features also come with great security concerns. At the same time, #Bitcoin can provide very high levels of security if used correctly. Always remember that it is your responsibility to adopt good practices in order to protect your money.
Some things you need to know
If you're getting started with #Bitcoin, there are a few things you should know.
#Bitcoin lets you exchange money and transact in a different way than you normally do. As such, you should take time to inform yourself before using #Bitcoin for any serious transaction. #Bitcoin should be treated with the same care as your regular wallet, or even more in some cases!

"Privacy is the power to selectively reveal oneself to the world."
-- Eric Hughes
Be Among Smart 8%
Only about 8% of bitcoin owners are estimated to keep their coins in complete safety and privacy. There are hundreds of bitcoin wallet apps. Most wallets are custodial, therefore — not secure, not private, and not independent.
Even if a wallet is non-custodial, it may still not be secure. Only reproducible wallets are completely secure. Mycelium is among them. Mycelium is the most popular among them.
“Being open source means anyone can independently review the code. If it was closed source, nobody could verify the security. I think it's essential for a program of this nature to be open source”
— Satoshi Nakamoto
“Completely non-reversible transactions are not really possible, since financial institutions cannot avoid mediating disputes. The cost of mediation increases transaction costs, limiting the minimum practical transaction size and cutting off the possibility for small casual transactions, and there is a broader cost in the loss of ability to make non-reversible payments for non-reversible services. With the possibility of reversal, the need for trust spreads."
— Satoshi Nakamoto
