I think the big problem is the amount of energy this thing is costing, and the huge load it puts on the GPU market, which could very much be a speculative bubble. There is a lot of difference between your examples and Bitcoin :

The labour of your employees hopefully adds something you can show to your clients : it’s a lot less speculation on your part.

Van Gogh is a name in the art world, and has a well documented place in art theory. Van Gogh is hardly speculative.

Point of correction: Bitcoin is mined with ASICS not GPUs
