There is no way you can recover it. Bitcoin transactions are irreversible. If you are lucky, the recipient may realize the error and return it to you though.

You could try sending a very small amount to that address with a message asking for it back.

Since you don't know how that address appeared on your clipboard, is it possible that you could have generated it yourself? Double check everything you did, you may already have the private key to it.

If you were playing with some program that generated that address and didn't save the private key, it is gone FOREVER. If so, consider it a cheap lesson in being more careful, others have lost significantly more due to carelessness (or lack of knowledge).

4,999 btc, enough value to run a heart for a month, their value must really drop in the future, maybe the standard is WorldCoin now, the new totally tracable cryptocurrency.

Don't forget to add some mystical symbols. Helps people believe in the magic of fiat currency.

Let's just go straight to satoshis, then we won't have to have these debates about the default size and names for units for at least another decade.

Due to distance & limited speed of light, every planet will need its own Alt-Coin. Time to start MarsCoin, you can take it (& migrate the blockchain) with you to Mars  

We should start a new slogan:

Vote for World Peace - Use Bitcoin

Besides, who would want to pay taxes with their bitcoins? I want to get rid of my fiat currency, not save it.

Looks to me that bitcoin keeps trying to get above $1000 and then losing support. I think we may have to wait at least a few more months for the infrastructure to grow a new price foundation before we get any serious growth in prices again.

So basically guessing around $950.

That being said, I am wrong more than I am right. Which is why I only buy and hold. I am good at investing (seeing the fundamentals), terrible at speculating (anticipating herd behavior).

Yes, the mining secures the blockchain. The 25 bitcoins that the miner receives is totally worth the security provided. You aren't the first person to misunderstand this process. It is partly a language thing, but using terms like "Securing" & "Securers" just doesn't flow easily off the tongue.

The Bitcoin protocol fits all together as a very elegant operation. When the media complains about one aspect or another about how Bitcoin works, it is a bit like complaining about how math, logic, or computers work.

Growing Wealth with Bitcoin

Bitcoin: Watch your money grow

Bitcoin: Money Tree

Watching the republicans & news media when Ron Paul ran for the republican nomination for president really showed how hopeless libertarian ideals are in a democracy. Freedom must attained through technology, not voting. Bitcoin is the gateway to freedom. Yes, us Bitcoiners may seem like religious fanatics, but this is comparable to when christianity challenged the power of rome.

We are talking about brainwallets http://brainwallet.org, not randomly generated public/private key combinations.

Certain precautions apply:

1) Open the URL in safe mode
2) Disconnect from the internet
3) Make sure your random words include a few numbers/upper caps/random special characters
4) Should use at least 21 symbols, words only count as 3 (even if the word is longer than 3 letters).
5) Never use a phrase that can be found on the internet
6) Close browser before re-connecting computer to internet
 
I would feel safe with something like:

GotchaKeepingMilkPP*5!=100+20*

The 3 words count as 9 characters, then add 13 more for a total of 22.
My brainwallet is actually longer and more convulated.
I would also suggest a paper cheat sheet for yourself just in case you forget it, something like: GKM PP ** 5!=+

Now to modify for a set of brainwallets do this:
GotchaKeepingMilkPP*5!=100+20*(1)
GotchaKeepingMilkPP*5!=100+20*(2)
GotchaKeepingMilkPP*5!=100+20*(3)
GotchaKeepingMilkPP*5!=100+20*(4)

or use call signs  http://en.wikipedia.org/wiki/NATO_phonetic_alphabet for extra salt:

GotchaKeepingMilkPP*5!=100+20*(Alpha)
GotchaKeepingMilkPP*5!=100+20*(Bravo)
GotchaKeepingMilkPP*5!=100+20*(Charlie)
GotchaKeepingMilkPP*5!=100+20*(Delta)
GotchaKeepingMilkPP*5!=100+20*(Echo)

Good point, that really obscures everthing.

Yes, they are just as secure.

SomeRandomWords(1) = 1P6WHE5KhHAyVRMCL51EqSUC5KN7BriwR7
SomeRandomWords(2) = 1nZ13beWGXKV5f6fPmP5rA1Aa1bxAQNrF
SomeRandomWords(3) = 1JgBvA258ZhZPpr2cLxGWrDVc6uu76Y2nT
SomeRandomWords(4) = 12Biw33Kfj6vQ3sTYWHSUiThMWjwRYwMzz
SomeRandomWords(5) = 1CAgiBZKQynkTwzqJTUMnpxA9jWQaPxuEA

Knowing that all five of those addresses are derived from a similar brainwallet phrase will not help anyone in figuring out the phrase.
Even knowing the associated key with an address won't help in deciphering the other ones.

Of course, if anyone manages to guess one brainwallet phrase, the rest will be obvious to them.

I bet Paypal is the first to add bitcoin storage and conversion to their site.

Ron Paul: Bitcoin can be a participant in bringing down the dollar

He seems to have some trouble due to that austrian economics theory that money needs to have intrinsic value, but at least he is open minded about it and the idea of competing currencies. Definitely more agile thinker than people a lot younger than him. E.G. Joe Weisenthal or Peter Schiff.

Apple is a cult of control freaks.

Why would you leave your bitcoins at Coinbase? Nothing against them, but you should always secure your own bitcoins. The only exception might be day traders, who have to leave some coins/cash on the exchanges.

I will eventually spend part of a deflationary money. Why not? The remaining amount will just increase in value. I just need to make sure that the amount I spend is less than the increase in value of my remaining money.

There is also the possibility of jump starting nucoin by importing unspent btc from the bitcoin blockchain. So nucoin wouldn't necessarily destroy bitcoin. It might be more like moving from ounces of gold to grams of gold. Everyone would still keep the value of their money.

Even if the designers of nucoin didn't like this idea, it still might happen. The people with a big investment in Bitcoin could just create an alt of nucoin using the cool new algorithm that gives nucoin it's advantage. But they would also incorporate the btc blockchain in this nucoin 2.0, maybe even allowing you to create nucoin2.0 coins by sending btc to an unspendable address with a message that includes your nucoin2.0 address.

The point being: Any new algorithm can be either added to the bitcoin protocol or, in worst case, will probably allow bitcoins to be migrated to the new protocol.
