Came across the thread earlier on Reddit and tried it. Pretty much fun. I used real money ($0.30) per post but you can get some Testnet Eth from the Rinkleby faucet(0), switch to Rinkleby on your Metamask plugin(1) and you're good to go. Also with Eth you can lower the gas(fee) all the way down to 0.1 gwei($0.01) and you'd still have impressive confirmation times. Far better than bitcoin at the moment in my modest opinion and Eth isn't even a currency. (0)https://faucet.rinkeby.io/ https://faucet.rinkeby.io/ (1)https://metamask.io/ https://metamask.io/
