Thanks for the video. I created an article that explain the difference between Rockz tokens: https://golos.io/ico/@cr1pt0n3ws/ico-ita-rockz-la-stable-coin-del-futuro
For ICO implementation, the ROCKZ platform issued Alprockz tokens. this is a token that runs on the Ethereum platform with the ERC-20 standard, this token is a utility token that will bring additional privileges to the holder, depending on the number owned. Publication and sale of Alprockz tokens is taking place at the ICO stage. Alprockz tokens, purchased during ICO, will provide ICO participants with lifetime benefits and bonuses.
