NFTs
Unique delegator NFTs (mp4) and Atari Quotes NFTs (gif and mp4) were created in the Atari BASIC programming language. Although they may seem somewhat old-school, we find a certain 8-bit poetics in them.
As a reward for our delegators, we distribute Atari NFTs after at least 3 epochs of delegation:
- Every delegator receives a unique delegator NFT.
- 10 - 100 ADA delegated - 1 of each Atari quote, random color.
- 100 - 1000 ADA delegated - 10 of each Atari quote, random color.
- More than 1000 ADA delegated - 20 of each Atari quote, random color.

Operator
CBROS was founded in March 2021 by two brothers that grew up in former Czechoslovakia (today Czech rep.). Since our first Atari computer in the 80's, over the wild and free 90's, then over our pirate FM radio broadcasting in 2007, we were still enthusiastic in discovering new technologies.
Today, CBROS pool is operated exclusively by Martin.

Since the 80's, when I shared an Atari 800 XE with my brother, I've been interested in computers. During my life in student's dormitory in the 00's I discovered the world of open source software and Linux and a few years later this experience led me to discovery of cryptocurrencies.
I see Cardano as the 3rd generation and ecologically sustainable cryptocurrency with a huge potential.
