Sharing new bitcoin addresses manually can get annoying, while reusing them is bad for privacy. Is there a middle ground?
In order to send a letter to a friend or family member, you first need to know their postal address. This means that some sort of interaction is required between you and the recipient, that is exchanging the address details, before the actual process of sending the letter can start. However, once the address details have been exchanged once, you can send as many letters as you want without even telling your friend about it. This works because even if your friend is not home, their mailbox is certainly able to receive letters non-interactively – allowing you to surprise your loved ones!Most readers of this article would probably rather send bitcoin transactions than letters, but the underlying process is actually quite similar: After the initial interaction of exchanging a bitcoin address, you can send as many payments to the recipient as you want, as the address will never expire. And just like a mailbox, a bitcoin wallet does not require any attention or to be “online” to receive payments – allowing you to surprise your loved ones with bitcoin as well!
