Is sharing my bitcoin adress safe?

[angelo]

I see post their bitcoin addresses everywhere. Is that secure? Can people steal bitcoins from those adresses?

[nobbynobbynoob]

No, you need to know the private keys associated with those addresses to be able to spend the bitcoin.

In "wallet import format", Bitcoin private keys are 51 characters long and begin with the digit 5.

Safe in the sense they cannot take the Bitcoins. Unsafe in the sense that it destroys your anonymity: they will know how much Bitcoins you own at that address (and possibly more depending on the transactions it is involved in)

in the bitcoin world there's two types of adresses: public key and private key.
a public key can handle incoming tranactions only( It's not quite like that, ask me if you need more info)

a private key is what makes you able to spend your bitcoins.

People usually posts their public adresses

The only thing someone can do with your public bitcoin address is GIVE you money.
It's not like a credit card number where they can TAKE money from you.
That said, the comment about revealing your identity is true to a certain extent. But that's all you're giving up.

No. They share public addresses. You can send them some money, but you cant take their money without knowing their private keys.

Open your Bitcoin wallet and generate a new address for receiving BTC. You can have multiple addresses if you want. That way, the public may know 1 or more of your addresses, but they won't know all of them.

It's the opposite of a credit card. In a CC transaction you give someone your info, and they take money from you. With Bitcoin someone gives you their info, and you send them money. The opposite is not possible.

Yeah as someone else said, it can revel all your transactions and show affiliation with other addresses.  This could be bad in some ways, like if you're gambling with satoshidice, everyone will know.  But really, advertising your address usually isn't a problem at all.  Definitely not a security risk.

I would post a secondary wallet with nothing in it and the minute something arrives there move it out to the "Unicorn Wallet"..
Just saying. May be a better move than posting your MAIN wallet. Most companies offer the ability to have multiple wallets like Block Chain from what I have seen over the past month of looking seriously into this!

Is it safe to stop working, give away all my (real) money and trust in bitcoin? I mean...will I get some, if I do that? (Post #4!)
