Please remove BitLotto from the list.

The site didn't pay out the March winner and it is still taking wagers for the April 5 lotto.

The last contact was from the (delayed) announcement of the March winner:

but no payout occurred and there has been no response to inquiries.

I wonder if it matters if your Mt. Gox account is verified or not.  So just to clarify you are moving EUR via SEPA to Mt. Gox (bank in Poland).  And your account is verified status (AML Level 1)?

But since UK banks don't like Bitcoin, you should not like UK banks.  Convert your GBPs to EURs through Transferwise or CurrencyFair and then fund your exchange account that way:

And then:

Just make sure it is uneconomic to attack.

The Finney attack is nearly 100% successful but it costs $4 per second to pull off.  So for anything sold worth more than $20, make sure to delay it a few seconds. 

A race attack isn't guaranteed to succeed (maybe one out of 40 attempts would succeed), but it is cheap to attempt.  But if I end up with 39 frozen burritos just to get the 40th one to spit out "for free", I'm not going to try.

Now let's say there is a change machine that converts bitcoins to quarters at a laundromat, with no fee.  An attacker could sit there all day and profit from the successful attempts and break even on all the unsuccessful attempts.  So that's not a good candidate for 0/unconfirmed transactions.

Neither.  Most are purchased and saved.   They are being saved to pay for future consumption.   Or as a simply speculative buy.

That is not hoarding.  

That also isn't necessarily a problem.

If bitcoins were not divisible, and there were only 11 million that could exist, then you'ld have a problem.

But instead of paying 1.0 BTC for a quick meal I now pay 0.1 BTC for it, the higher valuation doesn't limit me from being able to use them for my spending.

Because I can acquire more coins easily (with a bank transfer, sent to an exchange, for the cost of $0.25 per transaction using Dwolla, then 0.6% at my exchange) I'm not worried about using my coins for my spending.

But volatility is not good for a currency, so where a problem is introduced is when the exchange rate stops rising and those speculating on bitcoins start to dump.  Each sell puts downward pressure on the exchange rate which incents others to sell.

So that's why bitcoins need to circulate as part of commerce using the coins as a currency rather than just seeing Bitcoin used as a trading vehicle for speculators.

From the wiki:

- http://en.bitcoin.it/wiki/Confirmation

A digital currency exchange that sends out non-reversible funds when there is no recourse (i.e., withdrawn by an anonymous user) should not be considering anything less than 6 confirmations, in my opinion.

Of course, those funds in their wallet are not theirs (as they are customer's funds), so they can  be careless without exposing themselves to the risk.

I learned something new from it too ...


Back when first trying to remember how to spell it I broke it apart thinking maybe it was Casa Sci US  (house of science, U.S.).  I was way off.

locally? 

Which of the 163,707 square miles California encompasses do you consider local?

UK banks don't like Bitcoin.

So leave the GBP behind -- using Transferwise, or Currencyfair to get EUR.  Here's another thread on it:

When a transaction gets broadcast, that transaction gets relayed to most every peer node.  If your client was not running at the time, it might not know of the transaction because it wasn't online when the broadcast happened.   Eventually the transaction will likely get included in a block and then your node will see it.  Or the original client that sent it can re-broadcast it.  If the sender was using the bitcoin-Qt/bitcoind client then that will notice the transaction is not yet in a block and eventually will re-broadcast it (generally within about a half hour).

So if it is showing on blockchain.info then just hang tight.   Leave your client running so it won't miss a re-broadcast if you want the warm-fuzzy from seeing the 0/unconfirmed transaction in your list of transactions.

I think it is safe to assume no banks in the UK will work with any Bitcoin exchanges.  Any agreements to do so have a half-life measured in weeks.

I've seen where Mt. Gox only accepts bank transfers if it comes from your own account (and not a commercial account like Transferwise).  Are you able to perform this SEPA transfer method from Transferwise to Mt. Gox and they take it?    With SEPA transfer to BITSTAMP I've not read about anyone claiming the same restriction.

Which exchanges allow me to transfer funds from my TransferWise account?

The Bitcoin-Qt client takes care of everything so that a user doesn't need to know what a private key even is.   The keys are stored in the wallet.dat.

If you do want to see them, you can export them:

Any guess what this was about then?
