Here is the email I wrote to sell fastest.horse:
Hello, I'm James from the USA. I buy, sell and invest in domain names. I have fastest.horse (1000's of searches per month) for $500 paypal (or your suggestion). I imagine you can use this or sell it to someone. I am not around the industry. I just do this branding. It's a great memorable domain, FASTEST.HORSE
thanks
PS: Wish I had 123.horse
