I realise that most domainers here don't understand the potential this domain holds. "Altcoin" is not a brandable domain I own, it is a widely used term in the crypto community for bitcoin alternatives. Bitcoin has a marketcap of $3.31 Billion, while its alternatives, "altcoins" have a collective marketcap of around $500 Million. So a EMD for a 500 Million dollar "industry" has a valuation of reg feee?
If most domainers don't understand the potential this domain holds and you do, why are you posting it for appraisal?
I think the other comments were pretty spot on and you are looking at regfee to low $xx at best for reseller (remember reseller means other domainers so if we don't see the value, then that's the price paid for it).
Also, I think you have some confusion (well, generally most people do and there is no clear consensus) on what keyword vs brandable is. This one happens to live between the two. "alt coin" by itself is NOT a true keyword (at least not yet). It was a catchy term that someone coined (no pun intended) to be short for "alternate coin"... that in itself puts it somewhere into the brandable camp. Many brandables are plays on pre-existing words. However, it would be hard to trademark and brand it as an individual company since it is a term used by other websites and not something original (I'm sure a lawyer could correct/explain this better). That being said, using playful word variations and/or phrases that are commonly used is a common way for people to "brand" a website. Like I said, there isn't any clear consensus from the domaining community on where the line is drawn. So let's consider its possibility as a keyword domain:
Looking at the Exact match google search results:
"altcoin": 2,900/month
"altcoins": 1,900/month
"alt coin": 390/month
"alt coins": 390/month
"alternative coin": 0/month
"alternative coins": 40/month
Compare to bit coin (including the space typo) searches:
"bitcoin": 1,220,000/month
"bitcoins": 110,000/month
"bit coin": 49,500/month
"bit coins": 12,100/month
While I think we would all (including yourself) expect bit coin to be higher, those numbers for alt coin are hardly what I would expect to see in a keyword phrase. And "altcoins"/"altcoin" probably get most of their traffic due to pre-existing sites using them in the name and people looking for those sites, not necessarily the "keyword". As Azwan said, the "keyword" really hasn't hit the market at this point - whether it ever will or not is pure speculation at this point. Sure, there would definitely be some value in it for the .com version since it is a variant/alternative/brandable version of
the major keyword for a huge industry. But you are selling the .co which is inherently horrible for anything but strong keywords (outside of hobbyists, etc). The point the others were making is that since it doesn't have strong keywords its basically like selling a brandable .co which has little if any value. Whether it is truly "brandable" or "keyword" could be debated for the next 10 years. But I haven't see any "keyword" domains with that low of traffic selling for much if any in the .co world.
Reseller: regfee - low $xx
Enduser: low $xx - low $xxx (if you can find one...)
Hope this helps!
