wow thanks a lot! ..this are 2 very good links! -- also if this is not exactly what i am searching for, i am sure i can get something out from it!
while continuing my research, i could identify 2 different timeframes about crypto-art:
1. 2019 to 2013
2. 2014 to 2021
the second one starts at the early versions of NFTs, until today and is pretty good documented, cause its in the nature of NFTs, that they will stay FOREVER!
the first period was before the beginning of NFTs and art at this time was much more inspired by bitcoin and crypto, so the focus and subject was crypto, but the art wasnt necessarily build on a blockchain.
i could found 2 project up to now:
2011 - Mike Cadlwell

THANKS A LOT
