Are you saying you have previous made deposit and/or withdrawal but now your account history doesn't show any of them?

[p.s., Please try to describe your situation without using the term "wallet".   I've no idea what you mean by it.   A Bitcoin address is a Bitcoin address, not a "wallet".  A Camp BX exchange account is an exchange account, not a "wallet".]

Can I pay to charge a mobile with cash?

If so, expect that to also be paid for with bitcoins.

It maybe something that occurs in market stalls or by "friend of a friend" but it will occur.

Since the wallet has no provision to delete transactions, what you can do is export the keys, create a new wallet and import the keys.  Voila, your funds are spendable once again.

Your profit is limited.  So if you have gains, some or much of those gains could be taken.  That happened recently.


To have access to leverage for speculating in an environment which does not harm the privacy of your account.

Bitcoin allows a merchant to DIY or there are service providers as well.   The reason this reminder of "well-connected node" is described frequently is because a merchant that does it the DIY approach without following that little detail will get ripped off in a race attack -- a study determined 100% success by an attacker is possible if not configured properly.  The worst part about it, the transaction will appear, then disappear with no trace as if it had never been made.  So that is just a caveat for those DIYers.

In Nigeria they just dumped ID proof KYC requirements for low value bank accounts (i.e., under about $1K max balance).  Accountholders can open an account via mobile or online, without verifying ID (they have to give their name & D.O.B., but no ID necessary).

I'm not getting any success doing a spend.

I see the Javascript console:

If you were hoping to do CPU mining from a router, you are about 30 months too late.

Now using one to control an ASIC, yes.  Here's a related thread:

Are you the recipient of the payment (versus being the person who sent payment)?

If you are the recipient, perhaps you can spend the transaction (and include a fee) and a miner running "child-pays-for-parent will include it in a block.

GREEN LIGHT?    

Seriously ...  we got our first GREEN LIGHT for the weekend dip strategy in many months.



 - http://bitcoincharts.com/charts/mtgoxUSD#rg1zczsg2013-02-27zeg2013-03-14ztgOzm1g10zm2g25

The high in the past seven day period was $48.469.   The high in the seven day period prior to that was $49.099.

That's not much of a drop but technically it makes it a week-to-week drop, ... which means we're in a short-term down trend.

The weekend dip strategy says to sell at this level, with the anticipation of a drop.  Then to buy bitcoins back over the weekend at a lower price.

While we've had wild swings over the weekend before, they've been narrowing in degree.

But if the drop is down 5%-ish (quite common on GREEN LIGHT weekends), that would be a price around $45.

This weekend dip theory may be something that cannot be traded reliably anymore.  Who knows.  We'll see.

Something like this happened to me.  There is no e-mail verification and what I learned is I had signed up initially where I had typo'd on my e-mail address.  Then when I went to log in the second time, it was a completely different account, with zero balance.   

Fortunately I was able to figure out my typo by trying common mistakes I've made before and sure enough one had my funds.

One way you are able to tell if this is what happened is to look at the history.

If you played previously and nothing shows now, then you are on a different account.  If that is what happened, maybe coolidgecoin can help clue you in as to which e-mail address you might have used.

Private key to public key: Yes.

With serious amounts of funds at stake, you are correct.  A post on the Bitcoin Foundation forum might be a good place to raise this topic.


I was giving a "for instance".  I've no knowledge of anything like that being tried.   They definitely have the power to do that though (choose which protocol to use, then communicate that decision to the miners).  


The majority of mining capacity is needed to maintain having the longest chain.  

There's no contract from Mt. Gox to its accounts specifying that mt. Gox must use the longest chain and only that chain.  That is the protocol though and not doing so would probably not be something sane for Mt. Gox to do in most instances.   But let's take the reverse.   Let's say there was a catostrophic security breach at Mt. Gox and they put out code that would hard fork -- making the stolen coins and any that had taint worthless.   If the mining pools went along, they have 51% combined then the protocol would change.  If the mining pools instead ask around, they might conclude that taint would put into question bitcoin's survival and simply forge on without the code "remedy" offered by Mt. Gox.  The community can buy their coins at other exchanges, and then Mt. Gox shrivels into insignificance as a result.     That's a hypothetical, but I use it to describe that the "authority" is not the miners, not any single exchange, but those who will buy the mined coins.  

If Mt. Gox customers would stick with Mt. Gox and Mt. Gox has 80% of investor interest, then Mt. Gox can have a huge influence (as a proxy of its customers).   If investors will bypass Mt. Gox to buy the coins from the miners, then the investors have the authority.

The authority comes from whomever will buy the newly mined coins.

If Alice is "helping out" Bob, is this a loan, or gift, or income to Bob?

If income or loan, he would want to record each payment, qty and date.  The market value can be determined from the exchange rate under a few different ways.

So then let's say it was income, and Bob holds onto the coins the entire year.  He has income from receiving the coins at the value when they were received.   Hey may have unrealized capital gains at the end of the year but until he cashes them out (or spends them) those need not be reported.  

If instead this was a loan, and bob started repaying, all interest payments would be converted to USDs and he could expense that as interest expense.  But other than that it doesn't matter if the value goes up or down on the value of something that was borrowed.

Guilt by association.   PayPal's terms of service specify that you are not to use PayPal for trading virtual currency or other money trade.   The chances aren't that high your account (as a buyer) would be closed unless you really picked a winner to trade with right before that person pulled a big scam.   


Trust on the #bitcoin-otc Web of Trust (WoT) is gained through having a history of successful transactions.   As a party with low trust, you might establish trust using cash first (e.g., trading where you send cash in the mail, with another trader who does have a good trust history) and build a trust rating from there.   PayPal isn't impossible to trade -- it just is expensive and the amount you can trade small.  E.g., offer $30 for 0.5 BTC and you might get someone who will sell to you.

Different client have different backup needs and approached.

With Bitcoin-Qt, the wallet.dat contains every address plus a key pool for the next 100 unused addresses.    So you can back that up and at some point in the future restore that file if needed.

Other clients might use a deterministic wallet.  So with those only the master, spending of all BItcoin addresses created from that master is enabled.

A single address can exist in multiple wallets, that's not a problem.   What is a problem is if you try to spend from using a Bitcoin address that exists in multiple wallets simultaneously.  That's when you can gunk up your Bitcoin-Qt wallet.

But importing a private key from an old wallet.dat, and then later having recover that old wallet.dat is not a problem.   The funds will appear as being spendable in both.  Just remember to only have one running at a time.  (And don't spend until the client has sync).

What are you asking?

That would be bad for a miner as working on blocks that will never reach 120 confirmations means no mining proceeds.

(i.e., it could cause an orphaned blocks, and they might build on that and get two blocks or more but they'll never end up with that being the longest chain again, mathematically).

There is a patch for those who wish to mine using v0.8.   It will be released as v0.8.1 if I read correctly.

Draw a QR code with your Bitcoin address somewhere for extra points. (and monetary appreciation).

You could try messaging those from LocalBitcoins.  What occasionally happens is a trade request comes in and a single trader either can't accommodate the size of the transaction or is too far away, etc. -- so knowing who other traders in your area is useful info.

I see that Bitcoin Nordic accepts UKash purchased from South Africa, for trading to buy bitcoins.  It isn't cheap but in a pinch.


It's long past time to get at least one pin on the map for your continent:
