Which is why people charge premiums for it and most people will only sell bitcoin for paypal to people with trust. So when you sell for paypal, always check the feedback of the person you are selling to.

Search around look for the address. Try to think back on who you have sent transactions to recently. Check the transaction history in your wallet for that address and find the last time (besides this) that you sent to it. Really, there is no way to know who owns that address unless it was posted somewhere or you remember it.

Depends on who owns that address. Figure out who owns that address and let them know about your situation. If the person or service is trustworthy, they will send the bitcoin back. However, some services delete their old addresses after a few days, so your Bitcoin may be gone. In fact, I highly doubt you will get the bitcoin back, but it doesn't hurt to try.

That is not at all possible. No wallet would allow that, no node would relay the transaction, and blockchain.info would not accept that nor display the transaction. Your math is wrong.

Chrome can open html files even when not connected to web. In fact, I think all browsers can. In chrome, just type into the URL bar
where the path/to/file is the path to the file, including the drive letter in windows e.g. C:/

I will take a look at the sig tool update job and see what I can do with the program.

Also, is it possible to post for hire requests on that marketplace e.g I want people to hire me to do work.

You can try localbitcoins or the currency exchange section here. Either should be fine, but always check the feedback of the seller since you are receiving paypal. Paypal is reversible, so the seller could potentially scam you by initiating a chargeback. You can actually sell your bitcoin at a premium for paypal since you are taking the risk of the other person initiating a chargeback.

That happened with Coinut. A lot of people complained so the person running that campaign agreed to pay everyone for their posts prior to the announcement at the old rates and all of the posts after the announcement at the new rates. It is unprofessional for him to change the rates like that in the middle of the week, but at least he agreed to pay at the old rates for prior posts.

Supply and demand, what people are bidding for and asking for on exchanges. Those all are factored into determining the price of Bitcoin in fiat. It is just like how the price of stocks is determined, and the whole thing is highly volatile.

It is a large transaction with a small fee. It is over 25 Kb. A good enough fee for that should be at least 0.0025 BTC, but the fee is only 0.0008, which is too small for a transaction of that size. It should confirm eventually. If the money is going to you, you could attempt a CPFP transaction to get it to confirm faster, or you can just wait for it to confirm normally.

I would like to join this campaign.

I think you should be able to use the send many command: https://bitcoin.org/en/developer-reference#sendmany and have one of the outputs be to the change address. You would need to calculate the fee manually.

You need more RAM. You need set least 4Gb of RAM to run bitcoind decently well. I suggest that you upgrade your server.

What error are you getting?

The effective bit length is actually 136 bits since good algorithms like SHA 256 will require 2^(bit length/2) computations to brute force a single hash. This effective bit length will also change as the difficulty increases because miners will need to search through more nonces when there is a higher difficulty, so the bitcoin network would adjust to a quantum miner so blocks would still come out at around 10 minutes per block. So if we double the bit length by switching to SHA512, the effective bit length will also double so this will essentially make the quantum miners not anymore powerful than classical miners.

Your welcome. If you'd like, you can tip my address in my signature.

Maybe a massive buy or sell off due to the high prices now. It could be more transactions due to higher prices and thus more buying power. Or blockchain.info could have just screwed up again.

That is wrong. The hosting service has the option for a VPS with cpanel also installed. Since he has ssh access, he can do the stuff I posted above.

Well that's a problem.

I just checked the website and I think you are using CentOS 6 since that is the default linux version for vps with cpanel.

Type the following commands:

This will open up an interactive window where you can edit text.

Add the following lines:
where <YOUR USERNAME> and <YOUR PASSWORD> is the username and password you want for the rpc server. The password should be hard to guess and a random string of letters and numbers because knowing the user and pass means that someone could potentially send commands to the rpc server and steal all of the bitcoin there.

Then hit Ctrl+x and follow the prompts to save the file. Once that is done, start up bitcoind (or restart it). In the config file for the gambling script, set the RPC_Login and RPC_password to <YOUR USERNAME> and <YOUR PASSWORD> respectively. Make sure to keep the single quotes around each one so that it recognizes the strings.

Then you are ok. Just let it finish reindexing, it will probably take a few more hours.
