Madam/Sir,

This is the second time I am sending this email, after 11 day's
wait.Please provide a clarification for such activity.
I has already posted on vircurex thread about it
https://bt.irlbtc.com/view/49383.msg4497645#msg4497645

I have used the bitcoin address - 1N3vYYZ7ZkWEZ52wZ98kMkdC7bhh6CtyR1
given by you, for donation purposes.

So, I checked directly
https://blockchain.info/address/1N3vYYZ7ZkWEZ52wZ98kMkdC7bhh6CtyR1

to find someone donated me on 27 december 2013,but all the amount had
already been withdrawn.
Are you using internal addresses for transaction or vircurex is n't
secure any more ?

Let me first state, all is secure and what you observe is absolutely correct. This has to do with how the Bitcoin (or most of the alt coins in fact) handle the wallet transaction.

The address we give you, 1N3vYYZ7ZkWEZ52wZ98kMkdC7bhh6CtyR1, is for you to deposit coins, thus we know, anything arriving on that address belongs to you, hence whenever we see a deposit on that address we credit this to your account with us.

Now let me explain to you how - on a very high level - the Bitcoin wallet works when a withdrawal is made from that wallet. When you send coins (in this case when we - the exchange - send any coins to anyone) the Bitcoin wallet will choose (sort of random) various previous incoming deposits and combine them into one outgoing transaction. There is no logical link between the deposits and the outgoing transactions. This is just how these wallets work. Which means when another user withdrew some coins, the wallet was using your previous incoming transaction to fund that outgoing transaction. Your account balances with us are NOT affected by this.

In other words, the outgoing transactions from your address address 1N3vYYZ7ZkWEZ52wZ98kMkdC7bhh6CtyR1 are of no concern or worries for you. You have an account balance in our database that reflects your account, hence all your deposits, all your trades, interest collected and withdrawals.  You can withdraw those amounts at any time to your private address.

In short, there is no link between the balance on the deposit address we gave your for deposits and your account balance.

And this is very much the same way any exchange out there operates.

I sent an email but will post here just in case it wasn't seen.

I requested withdrawal of Nxt and it never arrived.

From account history

No trxID is listed.

I have Google authentication active for some months. there is a option somewhere...

Another thing, did the someone confirm that vircurex is not affected by the current ongoing wallet issues?

Yep.

Here's a prior withdrawal with a TrxID:
05 Feb 06:43   -1,426.00000000   NXT    Withdrawal, address: 3188455998465548903, TrxID: 9789294727222890658

I sent an email (customerservice@vircurex.com). I'm guessing that's not a ticket? Can you point me in the right direction?
