1  Bitcoin / Meetups / room sharing for Amsterdam Bitcoin conference 25-28 Sept 2013 on: September 19, 2013, 05:54:56 AM
I see there is not thread about possibly sharing accommodation, so I'm starting one.

If anyone is interested in sharing a room, with me, to save costs, contact me. Both if you already have a room and if you are still looking for one. Usually hotel rooms are for 2 people, even cheaper per person for 3-4 people, so if someone wants to group up, let me know, and we'll take a hotel or something!

I need a place for 3 nights, coming Wednesday. Preferably with kitchen access, as I am on a diet which is difficult/next-to-impossible without homemade food. Besides kitchen I need nothing fancy, sleeping on the floor is OK.

I arrive Wednesday in Eindhoven at 13:25, so will be around 16:00 in Amsterdam.
2  Bitcoin / Pools / a list of transaction inclusion policies of all major pools on: May 08, 2013, 01:29:43 PM
Is there anywhere a list of current policies of all major pools regarding including transactions in mined blocks?

The current default policy is described here:

27.000 bytes in the block are set aside for the highest-priority transactions, regardless of transaction fee. Transactions are added highest-priority-first to this section of the block. Then transactions that pay a fee of at least 0.0005 BTC/kb are added to the block, highest-fee transactions first, until the block is not more than 250.000 bytes big.

But as I understand it, pools can choose to have a different policy, and that can change over time.

It would be very useful to have a regularly updated wiki page with policies of all the major (e.g. having at least 1/1000 of the current global hashrate) pools and their current transaction inclusion policies.

Also the default policy changes over time, so when a change happens, it would be useful to know which pools have already switched to the new default policy, and which not.

Maybe lets start with listing available information in this thread, and then make a wiki page - preferably updated by pool owners, so we have reliable information aggregated somewhere.
3  Economy / Services / I will pay Bitcoins for professional advice/design of a soundproof room on: May 08, 2013, 12:17:21 PM
Maybe this is a long shot, but I'll try nevertheless:

I will pay in Bitcoin to a soundproofing professional who will prepare for me a custom complete design of a soundproof room according to my specifications, together with solving issues of heating/ventilation/water pipes which need to go through the wall, and the room should be soundproofed to 60 dB from the outside noise @1000 Hz (traffic noise).

I am considering both paying for a complete plan only (in which case you can be anywhere in the world) or also together with carrying out the physical installations (in which case you should be in Europe) - should be done by the end of summer 2013.
4  Economy / Goods / selling 7 silver coins on: April 16, 2013, 01:35:17 PM
Selling 7 silver coins for BTC, free worldwide shipping by postal service registered mail.

One of each of these:

US Walking Liberty Half Dollar
year 1943
0.900 Ag 12.5 g (11.25 g silver)
like this:

US Walking Liberty Half Dollar
year 1944
0.900 Ag 12.5 g (11.25 g silver)
like this:

Polish 1000   zł JAN PAWEŁ II
year 1983
0.625 Ag 14.5 g
like this:
these sell a lot over silver value, circa 30 USD on eBay, examples:

year 1975
0.750 Ag 14.47 g
like this:

And three of these:

Polish 200 zł "XXX LAT PRL"
year 1974
0.625 Ag 14.5 g
like this:

Total of 7 coins, total silver content: 69.9025 grams = 2.247417562 troy oz.

The "Polish 1000 zł JAN PAWEŁ II 1974" is worth about 4-5 times its silver value, others not much more then its silver value.

Place offers in BTC for the whole lot shipped anywhere in the world with postal service registered mail. Offers are biding once accepted by me regardless of what happens to the BTC/USD rates!

Will ship the same day BTC is received an address given to the buyer, buyer must pay first, my OTC rating:

Can also place offers for part of the lot, but I prefer offers for the whole lot.

Place bids in this thread, but don't pollute the thread with offers under 1 BTC!

I will end the sale once I see an offer I like and close a deal with the buyer.
5  Economy / Marketplace / is there a website which informs of all new Bitcoin-accepting places? on: April 16, 2013, 12:18:21 PM
I'd like to know of a website, preferably with RSS and E-mail feed options, that would be informing of every new place which has adopted payment with Bitcoin, every new online store or other service. A site where users can report sightings of new places that accept Bitcoin, but where there is moderation, so that for every new store that accepts BTC only one news item is released - I don't want to receive a 100 news items about Reddit taking Bitcoin, just one. Anything like that exists?
6  Economy / Trading Discussion / Bitstamp and BTC-E gone from "Pay to" at BitInstant? on: April 16, 2013, 12:12:15 PM
Noticed that Bitstamp and BTC-E are gone from "Pay to" at BitInstant.

That's not good to let one exchange monopolize the market even more, and being able to deposit with BitInstant to several exchanges is important for diversification of trade.

Any comments on why Bitstamp is gone and if/when it'll be back?
7  Economy / Currency exchange / whoever needs to cash out BTC fast (wire or cash) worldwide - pm me an offer on: January 10, 2013, 01:43:26 PM
Whoever wants to cash out Bitcoin to fiat, in the form of an express wire transfer (same-day or next-day), or cash from ATM (only if you expect regular need to cash out between 500 BTC a month - up to 15000 BTC a month), contact me with an offer, and we'll negotiate to work out an offer that is beneficial for both you and me.

Offer especially for people who want to avoid all the various hassles, and delays of exchanges. Don't want to wait days (or even weeks) for a wire transfer withdrawal from MtGox or another exchange? Contact me and in many cases you can see fiat in your bank account within an hour, or otherwise next business day.

You'd have to offer me a certain discount compared to MtGox - for the speed and convenience. Also no unexpected wire charges - what we agree is what you get - if you get less (because of intermediary wire fees) I refund the difference.

Regular, long-term trading relationships especially welcome, I can manage volumes in the range of up to 10000 BTC weekly.
8  Other / Beginners & Help / need to cash-out? get cash or free express wire transfer for Bitcoins same day on: June 22, 2012, 05:04:41 AM
Hi traders,

Every business day I am buying about 1000 Bitcoins.

Whoever needs to get a bank/wire transfer to their account or cash, especially regularly, send me a message.

Deals for same-day cash-out are done every business day by 09:30 London time. Current London time can be easily checked here:

Why sell to me instead of selling on an exchange?

  • I don't charge for wires - all bank costs are on me - I guarantee the arrival of the full sum we agree on, in the currency we agreed on, if any bank deducts a fee, I'll refund that.
  • If you want the funds on your bank account fast and not wait till nobody knows when for an exchange to make a withdrawal. In many cases I guarantee same-day arrival to your bank account - depends on bank and currency - ask me for details. Currently same-day guarantee is available at least for cash anywhere in the world in your local currency only (for regular BTC sellers only), USD transfers to bank accounts in USD anywhere in the world, and for EUR transfers to EUR bank accounts in EU, Norway, Iceland, Lichtenstein and Switzerland, GBP transfers to UK, and may be available for other currencies and countries - ask. If I guarantee, then if it doesn't arrive the same day, I'll refund 1% as a "late penalty".
  • Both guarantee refunds are available only on submitting an image of your bank statement with the transfer from me showing its date and amount as a proof - you can blank out irrelevant information.
  • If you want a specific currency, and not be charged your bank's currency conversion fees.
  • If you want cash - for regular sellers only, or a larger amount over some period of time.
  • If you want another payment method not supported by exchanges.
  • If you want a wire in a specific way not supported by exchanges.
  • If you don't want an international wire, but a national bank transfer - ask, and I may find a way, if not now, then I'll keep the country in mind and try to open a bank account there myself.
  • If you exceeded your exchange limits and want to cash out more without hassle.

Sounds too good to be true? What's the catch? You'll have to offer me a rate per BTC lower then current rates on exchanges. I only buy 1000 BTC a day, so simply the best offers totaling 1000 BTC submitted by 09:30 London time win. But because there are no wire fees, and you get your preferred currency, you might even make a better deal anyway. And because you get the money same-day, you don't have to cash-out so early if you need money for sure on a specific day, so you might wait for a day with better prices, and get a better deal then at an exchange anyway.

But remember: offers with a rate that I can buy at ANY exchange listed on that day will be rejected, I look for lower prices. How much lower? I don't publish prices, YOU make an offer: xxx BTC for yyy of your fiat currency, and if its in the 1000 BTC of best offers I got that day its accepted. If you don't get included that day, don't worry, resubmit your offer the next business day!

I accept offers by E-mail which I disclose in a PM only, I am not going to watch this thread for offers!

This thread is in the newbie section, so available to everyone.

PM me for details on delivery method, I agree details with a specific seller, depending on their location and needs, so I will not post in the thread about things I am offering just to one specific person selling BTC to me, but not generally (as not to have others demand the same) - for example the same-day guarantee or cash delivery, all such special deals are specific to one seller, and I might not want to offer the same deal to another person, because of limited capabilities, so they'll be discussed in private only.
9  Economy / Trading Discussion / is Bitcoin-Central maintained by someone? on: May 25, 2012, 03:08:23 PM
Is there actually a human supervising things at this exchange, or is it abandoned and will run until something fails?

Their stopped updating days ago (I did some trades yesterday and they don't show there), their support by E-mail doesn't answer, although I mailed them twice this month.

I wonder is it safe to put any money in this exchange any more?

I just withdrawn all my money through Bitcoin (bought at a loss - for more then I sold them there) from there yesterday until situation is cleared up.

I won't put any money into an exchange which can't even keep their bitcoincharts feed working - it means they're hardly serious.
10  Economy / Currency exchange / [CLOSED] if you have any Liberty Reserve, you can sell it to me - I pay by wire on: May 23, 2012, 02:04:50 PM
If anybody has any Liberty Reserve USD, and want to get paid for it by wire transfer, send me a private message with the amount of LR you have, what amount and currency by wire transfer you would like to get for it, the name and country of your bank (SWIFT BIC code if you know it), and if I'm interested I'll get back to you. You can also post in this thread, I'll be watching it.

I can also send you some Neteller, Moneybookers or Paypal but only for small amounts (when my wire costs would be proportionally too large for the trade to make sense).

Keywords for search: LR LRUSD sell buy trade exchange

[CLOSED] not buying LR at the moment, I may reopen later.
11  Bitcoin / Bitcoin Technical Support / why are my transactions sent without fees? on: May 20, 2012, 08:09:12 AM
When I send transactions (from client), when I look at them on they have no fees.

Isn't that strange, I thought all transactions now require a 0.0005 fee?

I don't have anything about fees in my ~/.bitcoin/bitcoin.conf

The client is from the Debian repository, daemon.

13  Bitcoin / Bitcoin Technical Support / Help, I started "bitcoind -daemon -keypool=10000 &" and its 18 hours already... on: May 15, 2012, 04:19:58 AM
Before I had keypool=1000 and everything was fine.

Now I started the daemon with:

bitcoind -daemon -keypool=10000 &

and it's been 18 hours and I still can't connect to it. When I try:

bitcoind getbalance

I get:

error: couldn't connect to server

It's version from latest Debian sid package (

Also when I try to connect to a locally (on the same machine) run webserver I get a timeout:
$ telnet 8000
telnet: Unable to connect to remote host: Connection timed out

I posted the last 200 lines from ~/.bitcoin/debug.log at in case it helps:

This is insane, its 18 hours already, what's going on?
How can I safely stop this madness?
Can I safely kill the bitcoind?
With which signal?
14  Economy / Trading Discussion / public Q to MagicalTux: what will you do if one can not prove where he lives? on: May 07, 2012, 11:43:12 AM
MagicalTux, I want you to answer this question publicly, so everybody knows and can make informed decisions weather to deal with you:

In one post you said: "Any document that proves you live at the address listed. A recent utility bill usually does the trick. A bank statement wouldn't as banks are not required to check you live where you get those sent. The registered address on an ID card wouldn't do either as most countries do not require you to update it if you move to somewhere else."

That is about what is required by MtGox to verify an account frozen by your AML team. So, lets say a customer opens an account, accesses the website through a VPN/TOR/whatever you think is a suspicious IP, deposits Bitcoin or MtGox code, and bach... your AML team flags the account and freezes it. You require ID (fair enough) and "proof of address" with your more-strict-then-any-bank rules. And here is the problem:

Customer can provide a passport, even notarized/Apostille/whatever, OK.

But the customer can't provide a proof of address. Simply has no way to go through this. This can be for various reasons, easy to imagine that lots of people will have no way to provide that to satisfy your rules. People who don't "officially" live anywhere, sleep at friends house, or outside, are in a country which won't issue them a "residency certificate" because they are ineligible for it, etc, lots of other reasons can be.

The only thing he can provide is a passport, plus maybe a birth certificate, let it be they are Apostille'd. Period, that's all the customer can provide.

What will you do next?

15  Economy / Currency exchange / can non-residents get verified on MtGox? on: May 04, 2012, 09:51:39 PM
My question is simple, I hope MagicalTux sees the post.

Can a non-resident get verified on MtGox?

If yes - how?

If not - why?

16  Economy / Currency exchange / does anyone know which BTC->LR exchange is reliable and "just works"? on: April 23, 2012, 05:07:14 PM
I am trying to exchange some BTC to Liberty Reserve.

Seemed to be possible with MtGox, so I transferred my BTC to them, waited over an hour, sold BTC for USD, tried to withdraw the USD, turned out their LR is dome via AurumXchange, went there, filled the form, and got a message "sorry we don't take MTGOX at the moment, try later".

WTF, changed my USD back to BTC, transferred to the next biggest exchange: BTC-E.
Again waited, traded, when tried to withdraw I got the message: "You have entered an incorrect purse". WTF? I mailed support, turned out they only accept 8-characted account numbers (U+7digits), while my LR account (opened 5 years ago) has U+6 digits, well, out of luck.

How can I stop wasting my time, and do it somewhere where it "just works"?

Site that doesn't have the feature down too often, withdraws Liberty Reserve fast and reliably?
17  Economy / Currency exchange / uses an invalid security certificate on: April 23, 2012, 03:00:33 PM
I am trying to access BTC-E with Firefox 10, and regardless of whether I go to or I get something like: uses an invalid security certificate.

The certificate is not trusted because no issuer chain was provided.

(Error code: sec_error_unknown_issuer)

19  Economy / Marketplace / is a scam? on: October 06, 2011, 09:27:41 AM
Since over a week I am trying to reach admin about transaction with a non-paying buyer via (transaction 14720), which I need to get cancelled.

My e-mails to are left without reply.


I am starting to think if they are pulling a scam now, and decided to disappear with users Bitcoins?

20  Economy / Currency exchange / beware of - buyers not paying, admin not responding for a WEEK now on: October 05, 2011, 02:56:15 AM
Beware of doing any transactions though

When a buyer is not responding, or unwilling to pay, your only way to recover Bitcoins is to e-mail the admins to cancel the transaction.

Now my e-mails about cancelling the transaction are unanswered for about a week, trying to reach someone at

Maybe the guy went on vacation or something, but heck, this is unacceptable.

You can guess what can happen with the price of Bitcoin in a week...

Don't sell any amount of BTC through the site that you would be upset to be locked up for days. Fine for selling Bitcoins worth of one coffee or lunch, but for anything more serious, wait until they have a more professional way of dealing with non-paying buyers (if that ever happens).

I am still waiting to unlock my 10 BTC from a transaction done 2011-09-08 17:04:50 - that is almost a month ago. Buyer claimed he paid, then he claimed he paid to the wrong account number and said he'll pay, now doesn't want to pay at all. 1 BTC was 5.23 EUR then, now 3.75 EUR. Even if they release my 10 BTC now, who will refund me the 15 EUR loss (exchange rate drop)? And this is not the first time it happened. If I add up all losses because of non-paying buyers with BTC price dropping while the Bitcoins where locked at the exchange it would add-up to almost a hundred EUR. Not a small sum for me.

Bitmarket says:

If you receive no response whatsoever from the other party within 24 hours please contact us. We will then send them a message ourselves and if they don't respond within another 24 hours we will (usually) cancel this transaction.

If they didn't cancel within 24-hours, might this be a basis for suing them for the losses?
