I'm not afraid of losing money. If you are indulging in speculative ventures, then you have to accept that you will have some losses. However, if your losses exceed your gains, then you need to do something else.
Very few people seem to understand virtual assets, and this includes Bitcoin and domain names. I believe that Bitcoin is the only crypto that is a hard asset, but not many people seem to be able to justify that comment, and they would include several of the alts as hard assets - I don't think this is true. Because of this, and the volatility of Bitcoin, I try to estimate its value in a year's time, and I use this for my personal calculations. I will almost certainly be wrong in my estimate, so I can't base a current sale price on this estimate, as buyers would be unlikely to agree with me. I want to avoid mentions of local currencies completely, as they have their own levels of volatility. The best solution seems to be to include a link to a currency converter such as xe.com, and allow the user to make his own calculation.
Domain names are an interesting investment. Each one is unique, and a good descriptive name can be a nice traffic magnet for a business. Alternatively, a start up company can take a simple non-dictionary word, and build value by branding it. Ebay is an example of this. The domain name must be worth millions now, but when they picked it up, it was probably only worth the registration fee. Selling names like this is selling dreams, and you have to find the right dreamer, and feed his imagination. This means that to a certain extent, it is a seller's market, but you have to make it easy for a buyer to contact you, and to pay for the name.
Escrow is a bit of a problem if it is required. The domain industry has nearly as many thefts and frauds as are associated with Bitcoin. A name that is transferred via a registrar push can be reversed, but it is far harder to reverse a registrar transfer. There are several honest and reputable members here who offer escrow services, but they may not be known outside the forum. An alternative might be to use my Jet Cash account to establish credibility. I own the domain
JetCash.com, so the account plus domain should have a reasonable value - possible into $xx,xxx. Godaddy values the name at $6,750, and that could be low. Couple that with some other names such as Baronets.com - $1,462, and BuyAny.com - $3,646, and it is obvious that I would be mad to throw those away for a few thousand pound fraud.
