I don't know how bitcoinnft works. Ethereum-nfts is a programmable coin or token or something. You can write things (contracts or apps to do stuff) inside that thing. I don't think you can write things inside of bitcoins. But these days they find ways to do it. some sort of attachment, layering or__?__. I'm too old to read up on todays news. I'll be like Isolabell and paint the traditional way. Competition is leading me to technology with art. Some make nft and then burn the original on video https://youtu.be/C4wm-p_VFh0
