"Is Domaining based on pure luck"
Domaining is definitely not based on pure luck.
Pure luck plays a little bit of a factor. Maybe 10%.
Domain Names are anything you want them to be. A tool. A collectible. A cheap investment. A high priced investment. A beautiful piece of art. A pc of crap. Something that makes you laugh. Something that makes you cry. A liquid fast trade. A long term generational valuable retirement asset, etc.
Buying and selling of domains are one of the most complex things you can do, or it can be one of the easiest things you can do if you have a huge bankroll. Most dont have that luxury so have to think hard about each dollar invested. Here comes the talent.
How you are playing the game shows the true talent.
Do you have patience? Do you want to renew that domain year after year? Do you have the money to renew that domain year after year? Do you do outbound sales? Do you wait for inbounds only and have the upper edge on that sale? Do you use a broker to sell that name? Do you pay for some marketing to push the sale of your name? Did you buy correctly, at a wholesale level? Or did you buy at a retail level/end user price? How badly do you need that money invested in your domains today?
All of these factors come into play when domaining. None of those involve luck. Its knowledge, passion, intuition, financials and balls.
I have domains i have owned for over 10 yrs that i have had offers on but have always quoted a high price on. Lets say i sold one at a low price here at auction. You win then you sold it for a high price. Ok little luck involved but you still had to bid against others to get that domain. You had to have the money. You had to list it somewhere where it could be found, etc.
Very little luck is involved in domaining. Lots of time involved though. Time is money.
It is amazing but many people do this for a living. Some people pay all of their bills solely off of domaining. I respect anyone who does so because i know how hard it is sometimes. I know sometimes even the big dogs lose money to keep the lights on. But then they keep churning and burning. Then there is that magical immediate no haggle sale that you have to accept from a broker on the phone right now in the airport right as you are getting on a plane because the buyer wants it so bad. Was that luck? No, Its all about everything you did to get to that point.
Pure Luck does not exist in domaining. If it did, i guarantee you that person who relied on a pure luck sale once or twice is broke as hell now.
In domaining, you have to work very hard to create your own, once in a blue moon lucky moments.
