What else is like domain name trading?

[wildomains]

What do you think will be or already is the nearest thing to domain name trading? I don't mean the stock market , bit coins or website trading. Think back to around the mid 80's when domain trading was just starting. What else could you register now for a few dollars that will go up in value later?

Any ideas?

Thanks
