You made me smile. Really cool. The simplest way to compare it but really effective specially to those who are still into Paypal. Here in bitcoin there is a better room where you could do something. Invest or trade or play with the fluctuation or maybe earn some loaning to someone.
Yes, with BTCs you can do many things, and with small amounts we can start learning trading, gambling for fun, investing. Good for children to learn about economy, investiment, etc. Crypto-currencies are educative currencies and very useful for who wants to make profit on medium-long term (holding), to have fun (gambling, using faucets), and trading to try some profit.
