Is there an automatic altcoin-bitcoin exchange service?

[konradp]

Hi,

I need to find an automatic altcoin/bitcoin exchange service, that is I need the following:

1. I have some altcoins on address A
2. The service allows me to send those funds to an address provided by them
3. I give them my bitcoin address B
4. After a successful transaction they send me bitcoins to address B.


Is there anything like this?

Some altcoin exchanges have an auto-sell feature which, when enabled, automatically puts all deposited funds up on the market at a predetermined price range (highest buying price, highest selling price, etc.). Cryptsy does that, as far as I recall. I don't know of any exchange allowing automatic Bitcoin withdrawals though.

Apart from what I have mentioned, which you can use to emulate the service that you're asking about to some effect, no, there is no such service that does exactly that.

Thanks!

I'm now reading this:

And I can see I can put a proposition to sell e.g. LTC for BTC, what I can't see is:
1. Where can I put an address to which BTC should be send after a successful transaction
2. How can I know there was a successful transaction?

Or maybe I'm missing something, and services like this work in a completely different way than I think they should work?

Carefull with the autosell feature. If there is no buysupport or a gap you might autosell way under value.
You can also set triggers on Cryptsy to only buy/sell at a certain price. I don't think there is an auto-withdraw function so you get the btc on cryptsy account.
