What a shit idea to use BTC network for this purpose. Why not use other chain already known for NFT Like Eth and Solona. Now we have to pay much high for sample transaction.
Why are people doing stupid things ?
Just because they can do them. As always on the Internet.
When you advertise immutability as BTC's selling point, it's going to attract lots of fish...
ps: ETH is not immutable (DAO 2016 hack) and Solana is in a constant beta-testing phase.
