Bitcoin, as you're know, is a new currency that can trade and use for online activities. I won't tell you about bitcoin itself because I'm sure you already know :). I just want to ask, why is so hard to get my first 1 btc with some free work. Like: ptc, ptp, faucet list 

Did you have an experience to get 1 btc faster ? Also, what's the different between bitcoin, dogecoin, litecoin etc. ?
