Saving securely with bitcoin, being able to change one's life, providing convenience in transacting quickly, this is an advantage of having bitcoin. Bitcoin has many who want it, but this must be stored safely by the holder.
Yes, and Bitcoin is the only payment method that is 100% irreversible and cannot be charged back. For this reason you should be careful when sending Bitcoins; be sure that you are sending them to a trusted vendor. As existing merchants will be well aware, when accepting credit card payments, or even bank payments the sender has the ability to reverse or chargeback the payment. There is nothing worse than sending products to a customer, only to receive a message that the payment has been reversed, you have been cheated and there is nothing you can do about it. Our life become more easy in the future. Right?
