Well, you are wrong "at the moment". If I was holding 10 BTC, I've already made $7000 in just a couple of days if I sell by now. Everyone has made profit already from bitcoins. Altcoin trading is a total battle. It's a zero sum game and whales are just lurking around. Some can dump all their coins and destroy everyone's hopes and dreams about that certain altcoin.
Altcoin trading surely has an advantage over regular bitcoin holding but only and only when you know what you're doing. If you're just about to start, I would say that you just stay holding your bitcoins and do some other stuffs. Altcoin trading can make you lose much more than money than you though.
