thanks for answers, now I have some information to learn. and one more question: if you want to invest in some alt, then what alt you prefer to invest in. (alt with some "mission" or simple alt that was created for speculations)
as a beginner you shouldn't speculate. you will high likely loose.
invest in innovations
(BCN)/Monero, MaidSafe, NEM, maybe still NXT
or founded coins
BTC, LTC, Peercoin or something...
Of course you will be probably drive best on newest innovations. The problem is, that you can't see then that good as a beginner.
