Congratulations on figuring this out. The trick now is to find which ones have a potential future and which ones don't, as you are right in 5 years a lot of these so called "alts" won't survive, or still be worth pennies if they do.

Of course I think a lot of people actually do realize this truth and are just playing musical chairs taking advantage of the profits offered by the pump and dump nature of these coins. Just don't be the one left holding the bag when the music stops.
