I'm sorry. I just can't follow the logic of these NFT's. The link shows the Tom Brady autographed NFT. You can capture the video. Now granted it's not numbered but you can view it as much as you want. Here is the thing. If I get a Tom Brady autographed card assuming it's authentic I know Tom Brady physically signed it with a sharpie. Why should I get excited about an electronic signature. Tom Brady never actually came in contact with electronic signature. He signed what amounts to an electronic Etch-A-Sketch. Each physical trading card Tom signs is a little unique because a hand is not a robot. The NFT is nothing more than computer code. Would you want an electronic signature from Babe Ruth or an autographed baseball that Babe actually held in his hand while signing it. I realize dozens of people handled the Babe Ruth ball before I bought it but at one point the Babe himself held the ball in his hand. I can also display a Tom Brady autographed football card or Babe Ruth ball on my mantle. Imagine having some friends over and saying do you want to see my computer generated Tom Brady signed card. They would laugh at you.
