By the way, that jankekek's comment about cryptopia's deposits and withdrawals reminded me that there is indeed a problem with the interface of the site. When I open either the deposit or withdrawal history, I see a table with all the relevant data like "currency", "amount" etc. One of the most important columns in those tables is "transaction ID": when a withdrawal is "stuck", for example (ie it says "complete" but nothing arrived to the wallet after an hour of waiting), I copy the TX ID and paste it into a blockchain explorer to see what's going on with the transaction. Except cryptopia's tables are broken and they don't display TX ID's properly:
The only way to actually get the full TX ID is to export the table (and btw, your PDF's are also broken, although it is possible to copy the full TX ID from the PDF — it's just the formatting that is messed up there). I don't think that's how it's supposed to be, all the other exchanges I've been to don't have this kind of problem (and some better ones not only display the TX ID, but present it as a link to the blockchain explorer website so the user doesn't even have to copy/paste).

Double click on TxId , copy (Strg+c) , paste in blockexplorer (Strg+v) , Finish !

Just imagine with how many transactions the blockchains would be loaded with if every order on an exchange would actually go through the wallet. All those bots doing buys and sells 24/7.. blockchains would explode. Not to mention the time it would take for each transaction. I'm no expert on the internals of crypto exchanges, but I'm pretty sure all the trading goes through some kind of internal database. You deposit some coins to your exchange wallet, and then the number (and type) of coin gets recorded in the exchange's database. Whatever trading you do with those coins never really has anything to do with the coin's wallet, only the internal database of the exchange gets updated with every trade. And when you decide to withdraw something from an exchange — that's when the wallet gets involved and an actual coin transaction happens (through the blockchain).
