these coins are not worthless to developers who need the coins for testing
They are worthless, but useful. They are useful because they are worthless. If you will add value to them, they will be useless, therefore worthless.
Are we still talking about bitcoins? I think that can be applied to fiat currency. lol
I have always said that fiat was worthless until someone works for it. ah never mind.
I'm sure someone will get it out there in the internets

I forgive him
