I just sent some NFTs...if you didn't get one, let me know. Yes, WAX via AtomicHub is the easiest that I've used, followed by Phantasma and then NFTshowroom. I started with OpenSea and although it was doable, I had to take notes. For whatever it's worth, my breakdown: AtomicHub/WAX is easiest and cheapest, Phantasma is powerful and I need to learn more there, NFTshowroom is best for artists, Eth is expensive. I wrote about the first three chains at https://peakd.com/hive-167922/@crrdlx/nfts-how-to-mint-nfts-information-using-various-blockchains and Hive at https://peakd.com/nfts/@crrdlx/how-to-mint-an-nft-on-hive-using-nftshowroom
I like your tutorials. I just bookmarked them. I will probably need them later on ;-).
And thanks a lot for the NFT's. I first didn't see them :-)
