Thanks guys!

Hi guys,

I'm a newbie in Bitcoins.
I used to do trading on stocks and now i would like to try the same thing on bitcoins. I want to know if it's possible to buy and sell bitcoins with fast operations (seconds or minutes).
I want to trade directly bitcoins (or other cripto-currencies) and not derivative instruments, but I read that, to complete a transaction, you need to wait the confirmation and this can require hours. It works like that? Are there some workarounds?
