Advicing people to do gambling isn't the right thing to do. Even though I put "investing" in altcoins also somewhat in that same category, it still needs a tiny bit of experience. I say 90% luck, and 10% experience since it's a speculation driven part of the market.
A very good observation though, i do agree with your statement regarding on altcoin trading which is somehow usually depends more on luck than skills since the price is very unpredictable, if you do have the skills but luck isnt there on buying a certain altcoin then you would surely suffer loss. We could really start trading even on small amounts though on alt tradings.
