bitcoin address not valid

[Aztec]

Hello I tried this out http://www.bitcoins4.me/ and its telling me my address isn't valid. I'm using Bitcoin QT and it generated the address for me so not sure why it isn't working. Are there other ways I can tell if the address works quickly?

Thanks

J

Also, is there any risk submitting your address to public sites and forums? Could the information assist hackers? That's the only reason I can think of for people giving away BTC

It works for me so I guess your address is really not valid.

It should look something like 12fuR1FF753m9E5PKiK6wU7RSHX23WoQng

Could it be that my wallet is still syncing with the network?

PS thanks for reply

[Gator-hex]

Can take 2 days to sync with the network.

Are you trying to move an old address into a new wallet?

If so you need to disable the network connection, make a new wallet, copy the old address book in, then enable the network and sync.

No Gator I have never done any transactions yet. I just installed the wallet around 2 weeks ago and clicked on the button to make me an address to receive coins. I tried generating a new address and that one was ok.

Make sure you don't have any extra spaces or other invisible whitespaces (tabs, carriage returns, etc).  A good site will strip that from the webform before validating but some don't and return false positives (i.e. mark "1AxkyqHW98DMH1mZiXZ247BYdDvwN4dV9U" as valid but mark "1AxkyqHW98DMH1mZiXZ247BYdDvwN4dV9U " as invalid.   You can always try another address.  Your wallet can produce an infinite number of addresses.  If you try more than one, are sure you don't have any extra whitespace, and it still says invalid then their site is broken (possibly flawed address validation).

If you want you can post the address here, or PM it to one of us and we can tell you if it is valid.

No and all the comments about resyncing, copying wallet files and other nonsense are off the mark.  An address is valid or it isn't. It has nothing to do with the blockchain.  You could compute and address by hand using pen and paper and it is valid or it isn't.

When you receive bitcoins, your bitcoin address is permanently stored in the VERY PUBLIC blockchain that every full node has a complete copy of.  If having your bitcoin address could assist hackers in spending your bitcoins, then bitcoin wouldn't exist.

The reason these websites are giving away incredibly small fractions of a penny worth of bitcoin is because they are being paid to display advertisement banners.  They use the promise of "free bitcoins" to get you to see the advertisement, and then pay you such a small amount that it is really pretty useless.  You may even find that you have to pay more in transaction fees than the "free bitcoins" are worth when you later try and send them somewhere.

Thanks for all the replies guys.

@DeathAndTaxes I copied the address from the wallet and pasted it straight into the textbox on the site so I'm certain there was no white space.

@BurtW thanks This is the address in question: 18mKqo57VSmxq1ecUZ5Uu2DYNZdjCaeFa

@DannyHamilton thanks for clarifying that. It makes much sense. I just have gold fever. I'm making peanuts with my HD5850 but am quite addicted to it, especially while the exchange rate climbs. Wish I'd have been into this sooner. I'm always late to the party

As far as I can tell, that is a valid address.

As far as I can tell, http://www.bitcoins4.me/ does not recognize that as a valid address.

I believe this is a bug at http://www.bitcoins4.me/

You can try and contact them and let them know that their website is broken.

I sent you some spare change from Electrum client. Address seems to be OK.

Thanks man I appreciate the help. Will that now show up in the transactions in my wallet?

Only when you finish the the blockchain sync. (Can take days!)

No contact info I can see on their site. Did a whois but couldn't find an email address.

It might be a bug with our decoding to base58, I will look into it.
I will also add a contact form soon. If you have future inquiries, use this topic:

Sorry for the inconvenience!

No inconvenience man. Thanks

I've also had this problem at ...
http://www.bitcoins4.me/

and also at
http://www.elbitcoingratis.es/

both of them said my address was invalid though i have used that address successfully on about 20 sites ...

It's valid - see your balance here if your client has yet to sync: https://blockchain.info/address/18mKqo57VSmxq1ecUZ5Uu2DYNZdjCaeFa

I don't know if you figured this out yet but I just replied to this in another thread:

Hey!
I just announced my new site, bitcoins4.me! You can get bitcoins for free every hour, just by submiting your address. Payments are made in about one day.
You can keep track of updates in this topic.

 

If any of you try it out let us know if you get a payout.

I've tried this site ...
http://www.bitcoins4.me/

and it says "Error! The address is not valid. Try again."

and this other one based in spain ...
http://www.elbitcoingratis.es/

which says "ERROR: La direccion de tu Bitcoin Wallet NO es correcta, compruebala."

... So two different sites saying that my address is invalid although I have used this address on about 20 different sites with no problem .  Anyone else getting this ?

I have noticed this too with bitcoins4.me.  Is the address you used less than 34 characters? 
It seems that site rejects valid addresses with less than that number of characters even though there are valid Bitcoin addresses which have only 33 characters.

Just use another address for that site until they get it fixed.
