There is literally nothing in those selfies. He's not chris hemsworth or amelia clarke. Still we can give him credit for something as he showed up with product.. imagine there are pixelated avatars like Punks being sold for expensive ethereum value. It's like even brick in 90s arcade game can be sold for a price.
If you record your cats meow and sell it as NFT I won't be surprised that too would get sold. Crazy people with money in this decade.
