I think closing it down would be a horrible waste, should just keep controlling interest in it and turn it over. If they do not run it up to par you can take it back over plain and simple. At least this way you have a chance to recoup your money instead of just kissing it good bye.
They lose money every month on it, closing down would be a sensible thing to do. More sensible would be to sell cheaper. Its better to get something than nothing.
And yes, the software etc is all worth more than the opening bid. Except that your buying a business, not a custom script. Thus you sell at what the business is worth, not what you paid for it
Your logic doesn't make any sense, you agree the software is worth more stand-alone, but that same software tested and running live/doing trades/having around 500 free visits daily/getting around 20 users daily is somehow worth less? On the contrary the software stand-alone would actually be worth less, although not by much as I've priced this auction very competitively already.
Also, we did not just buy a "custom script" as you suggest, I thought it was clear we are engineers by trade who made everything from the ground up and completely tailored to cryptocurrencies.
I think it's fair to say you are not interested AcoinLLC, you seem someone who invests in small businesses expecting a steady, mostly passive return. Running a financial exchange is obviously not something for you, it's a very serious project to take on I really want to warn people for that, this is really not something that can be approached like you do small businesses. We can argue all day about what you think is a fair price but it's really rather pointless.
