Some non-fungible tokens are so non-standard that they can even be called crazy. In any case, they either have already brought some money to their owners or will bring some profits in the future. For example, Grames' WarNymph Collection sold for 5.8 billion USD, and custom-designed toilet paper was auctioned for 4,100 USD. The digital source code of WWW gave its creator 5.4 million USD, and the random set of numbers in “The n project” brought 4,500 USD for each unique single number.
