Hello, I received this image from a blog. I believe it is an opportunity to start mining or instituting cryptocoins.
Obviously this is just a hoax, the blog that you got the image maybe untrusted or/is used as a way to pump both zcash and bytecoin.
People will always find ways to promote what ever they want in believing that someone will invest it zcash or bytecoin because a big company like walmart is investing in the coin.
