Well, problem is: If there's 1 new altcoin every day you have to keep buying. Only a low percentage of them will even make it to something reasonable (or even overtake Bitcoin, it's possible of course), but the others will go away at some point during your 2 years.
It's very tempting, but just simply buying a little of all of them isn't going to cut it, because the 80% failures will eat the profit of your 20% profitable ones. You'll need to do research and evaluate the fundamentals, apply your personal preferences and then only buy the promising ones... much work. And then your analysis needs to turn out to be more right than wrong.
Hate to break it to everyone with $$$-signs in their eyes: there's no free lunch.
EDIT: not to discourage people to invest in alts, just to caution and remind to apply some basic brain functions first.
