Then let me explain it to you, since you admit your complete ignorance:


Step 1:  Hear about Gridcoin
Step 2:  Buy Gridcoin on Poloniex
Step 3:  Continue your life every day like a normal person, check Bitcointalk sometimes
Step 4:  Go to Poloniex one day and find out:  "These coins are worthless now, thanks for your money dumbass, fuck you."
Step 5:  From now on, make sure to tell everyone that Gridcoin ripped you off


That's how it works.  Glad I could help, let me know if you have any more questions.
