But in the original bitcoin client by defoult its disabled the option for faster transaction, and I belive there are no fees if you wait longer ?

I got one payment from a minig pool 50btc of 0.1 coins, and I bougth 1 time from a website from bitcoini.com for 0.10 coins, and my wallet is at 0.11 now.
However I did not spend any to see if I will lose some of the coins over the transaction.



Also I used a few sites on my work computer to get free bitcoins but when I saw they pay in mBTC I stoped to use them .
