Selling Test bitcoin I have a random and maybe crazy question. Can I sell test coins? Someone recently told me that Advanced Market Terminal is buying them. It is strange to me Since they should hold no value.
Testnet coins are an interesting thing:

They are useful because they have no value
If they had value, they would be useless

Remember that the testnet is there to test out your code, and ensure that everything runs smoothly before you deploy that code to an environment which is holding actual value. That way, if something goes wrong, you haven't lost anything of value.
So you certainly could sell someone testnet coins, but I'm not sure why anyone would pay you for them.
