what security factors have to be considered in order to create an "ideal" exchange today ?
basic examples : transaction malleability, ddos attack, ensure perfect entropy in generators.. ect

btc isn't technically better, the but it was the first one released and has the biggest user base & market cap

I guess : the last number to be guessed : x

"never invest more than you're willing to loose" that's true for penny stocks, futures... and even more true for unregulated crypto currencies

Being confused why there no US based exchange at the moment, I did a little bit of history.

I read that tradehill was a US exchange that closed because of "regulations" and other issues ?!
I think coinbase would be much more legally liable than an active exchange since they are selling their own coins and not just facilitating exchanges...
Will another US based exchange thrive ? or are people too afraid of government regulations to invest in creating a USD<>BTC exchange ?

lol ! you're pushing it

what would be the language of choice to create a secure and relatively high volume orderbook used on an exchange ?
thanks !

ok thanks for the reply,
but at the beginning of coinbase for example,
how did they gather enough buyers and sellers to make the transactions ?
is that what the 4 days delay was for (besides the ACH approval)  ?

what happens if
one guy is selling btc4.235 at $840 and another guy is selling btc6.135 at $735
while a buyer i buying btc2.435 at $751 and another buyer is buying btc7.139 at $813
since the price is so volatile almost all transaction will be made at different prices, how is it possible to match up buyers and sellers ?

I've been trying to figure out how bitcoin exchange services work. Specifically the ones that allow you to exchange btc for fiat money and viceversa.

for example

If I try to buy 2 bitcoin:
1-are they going to give me a coin that they already have ? or
2-are they going to give me a coin that a seller is trying to sell ?

if they give me a coin they already have, how do they now they'll always have enough to supply all the buyers ?
if they give me a coin that a seller is trying to sell, how to they know that they will always have enough volume to satisfy all the transactions ?

finally is this entire thing managed by some type of database, oracle? sql ?

thanks !

so how can they allow instant exchange by linking a credit card ?

I was inquiring more about the technical aspect of the exchange.
where do they get the coin to trade for your USD ?
thanks

Hi, I was wondering how coinbase can take your USD and change it to bitcoins ?
did they somehow gather a lot of coins to start with and then allows people to buy and sell coins from their wallet ?
do they have a direct connection to other bitcoin trading website so they can tap into their reserve as well ?
how does this whole USD>Bitcoin exchange works ?
thanks for your insight !
