I prefer Litecoin because I know that ripple at the month of January increases while the other altcoins are dropping, but for me, it's just the strategy of ripple to attract other people to invest with it. If you only observe the ripple movements today, the value of it actually dropped. Well, most of my friends keep on saying that it is a scam which seems to be true. Litecoin is a good choice of altcoin.
