I understand OP's statement, and I would agree to warn new crypto-fans to invest heavily in new coins. The risks are just too high to bet serious money. On the other hand -- if you have the time and/or money to spend -- it's fun! I'm playing around with a bit of cash I can lose.. and it's fun to be part of budding crypto-communities.
Despite all the big ambitions, don't take alts too seriously. If one or more alts make it to the mainstream, just be sure you have a wallet full of those silly coins :-)
