At Cryptsy the order is First In First Out influenced by the account's trading history. If the server were to receive buy orders at the same time assuming there is enough coins at the specified price to fill the orders, the server looks at each account and the one with the most trading history gets processed first, then in order to the account with the least ...

I'm not sure when you say "If I buy half a bitcoin at $500" whether you mean you paid $500, or whether you mean the price of one bitcoin was $500 and you paid $250 for half a bitcoin.
If you buy half a bitcoin for $500, that means the value of one bitcoin is already $1000. The price can not increase from $1000 to $1000.
If you buy half a bitcoin when the ...
The usual process is this:
You create an account on the exchange.
You go through their menus to deposit bitcoins.
They give you an address to send bitcoins to.
You withdraw from Coinbase to that deposit address.
You wait about an hour.
You now have a bitcoin balance on that exchange that you can trade.
263.95 [USD/BTC] / 233.56 [USD/BTC] * 1 [BTC] = 1.13 [BTC], i.e. for each BTC you sold at the higher price, you can rebuy 1.13 BTC at the lower price.
The underlying concept is explained on Wikipedia: Cross-multiplication.
The trade engine itself does not withdraw or deposit coins. It would be terrible for the exchanges, because it slows the trading down enormously, and also the fee they collect is reduced (or the fee you pay is increased).
When you want to withdraw some coins, the site checks the wallets they own who have enough balance. From one of those (Im not sure how ...
You have to get money into the exchange to purchase and secure your position somehow. BTC is probably an easy way to do it but you could also do it with EUR or USD. You will need BTC to close the position but since you're going to be shorting BTC, you won't want to hold BTC while the position is open, so you'll be holding some form of fiat instead.
Yes, it is probably cheaper to have your friend send you an altcoin, but if your end goal is to own BTC, then just have him send you BTC. I say this because:
The exchange you're going to send to will have its own fees (trades/withdrawal fees are common)
Storing coins on an exchange is not a good idea, if that exchange closes or gets hacked, then your coins ...
Marketplaces (as well as ATM's for this matter) typically require you to send the bitcoins to an address of theirs. As soon as that transaction confirms, they send you cash via a traditional bank account, paypal etc...
Any trustworthy marketplace will describe that process in detail. Here is some information from btcdirect, for example: https://btcdirect.eu/...
Technically you don't earn anything until you sell it. So just consider it like any other commodity:
Start off with 0 bitcoin and $500
Buy 0.5 bitcoins for $500.
You now own 0.5 bitcoin, and $0. You've exchanged one item, dollars, for another, bitcoin.
Bitcoin price goes up relative to the dollar.
You now own 0.5 bitcoin, and $0. The amount of ...
Bitcoin is like any other investment, you will profit/lose the percentage Bitcoin changes on your capital investment.
If you invest 100$ into Bitcoin and Bitcoin increases 10%, you will earn 10% on the $100.
If you invest $10 into Bitcoin and it drops %50, you will lose %50 of your initial investment.
With there only being 21 million Bitcoin possible to ...
1 kg tomato is $10,000 today.
If you buy 1/2 kg tomato today, you would have paid $5000 today to buy that.
If 1 kg tomato becomes $20,000 tomorrow. What you have in hand is still 1/2 kg of tomato. but you can sell that 1/2 kg of tomato for $10,000.

If you are looking at the btc_usd pair, then the price is in USD, and the amount in BTC
It just depend on the site you are seeing, on market charts/stats (like http://bitcoincharts.com/ or http://bitcointicker.co/) volume refers to trade volume, which indeed is not the money sent to the exchange, it is the BTC that changed hands inside the platform (there is no need to come from external and the same "coin" can be traded several times a day).
The same way gold or any commodity did, the person buying bitcoins valued the idea or thought it had potential and payed someone money for their bitcoins. Price is what people are willing to pay anyways. Mining is the same concept, miners are paying with their hashing power (it isn't worthless!) to the bitcoin network.
It was as shabby and undocumented as ...
As of October 2012, it was determined that around 78% of all bitcoins minted (as of May 13 2012) were being hoarded "in user accounts that have never participated in outgoing transactions", meaning that all other trading and commerce was actually being transacted with a "float" of the remaining 22% (i.e. less than 1 in 4); and there is really no way of ...
The issue with FinCEN and Regulatory compliance is this- How do they know that the Bitcoin Mr X is trading, exchanging, using, purchasing etc was not just gained for the sale of child porn, drugs, internet gambling, etc. A credit card company can block internet gambling, it can disallow the use of its card to openly pay for illegal stuff like drugs, ...
Regulators have not yet really figured out how to deal with Bitcoin, so things can change in the future.
It should be noted, however, that a Federal judge in Texas has ruled that Bitcoin is a legal currency. This came about when a guy set up a Bitcoin ponzi scheme and then tried to claim that he couldn't be persecuted because Bitcoin isn't a real currency. ...
Right now Bitcoin is the round peg in the regulator's square hole.
If Bitcoin is deemed to be a security, then certain restrictions might apply on how it is bought, sold, and held. But Bitcoins themselves are not a debt, or a promise, or anything similar so it probably isn't a security.
If Bitcoin is deemed to be a commodity, then certain restrictions ...
