Wow, that's quite an impressive piece of artwork! Your haptic Bitcoin transaction looks fascinating with those colored layers of wood. It's like a visual representation of the digital world merging with the physical realm. The decision to sell it or hang it on your wall is a tough one indeed. On one hand, you could make some Bitcoin gains by selling it, but on the other hand, having such a unique and captivating piece displayed in your home would be quite the conversation starter. Either way, kudos to your creativity and craftsmanship!
