Coincidence or Not

Hi everyone, hope you are all doing great. I created this NFT on Nifty ink on September 6 2020 and named it Polkadot. A year later a well known artist named Damien Hirst dropped nearly the identical NFT as mine, and made millions off of it. It went on to be a very successful NFT and I'm sure most of you are familiar with it. Please give me good advice and judge for yourself . Thank you for your time
