Advice wanted: Using One Address

[Reynaldo]

Just use vanitygen and generate your own unique address

Download the window binaries, run it, import the privatekey of your new address to your wallet software (electrim bitcoin-qt armory, etc)

and then just proceed to use it.

Fastest tool ever...but an update would be great for still a better performance

There is a potential problem with reusing public addresses, the reusing works by "accident", not by design.
It is considered a bad practice, and not something that should be done. Nevertheless I personally have a vanity addy which I reuse for small transactions.

The security part: as long as an address only received bitcoins, only the address is known. But once you spent some coins from that address, its public key is known (public address is a double hash of a public key). Theoretically, having your public keys out there could be more vulnerable than having only their sha256+ripemd160 hashes out there.

Very interesting - thanks for this, I had no idea that this was the case.

I would use multiple address for each transaction.

So I can record them easily.

using one address is ok as long as ur ok with people knowing how much btc u have. its also a good idea for merchants as customers can always verify they've  paid you

Hi folks, newbie here. I'm looking for some advice please.

I really want to have a permanent public address that I use to receive Bitcoins. By this I mean that I use this address everywhere online (and on my business cards). Anyone who wants to can then check my name and address online and see what address is mine.

I've seen people talk about privacy issues but I don't really understand why. If there is a problem with doing this, is there anything else that I can do to mitigate the risks?

I've seen onename.io allow you to do this so I'm assuming that having one address that you publicly claim s yours can't be too much of a problem.

Thanks!

The advice comes from Satoshi's original paper.

You might want want to read it to know his reasons, but you are not obliged to follow the advice and might have your own reasons for not doing it

True. When your public key is known, the security is lowered from 160bits to 128bits. But the good news, it is still impossible to brute-force your private keys.

So if OP doesn't carry much about the privacy issue, it shouldn't be a problem.

take a look at vanity addresses, you can create your desired address and even put your name in it.
