The truth is that you require at least one year’s time to get around only the basics of the domain flipping business, leave alone making huge money from it. During this time, you’ll make several mistakes, buy useless domain names, lose out prospective deals and much more. Domain flipping is far from any get rich quick method. If overnight results are what you’re after, domain investing may not be your piece of cake. This business involves a real and steep learning curve which many people find difficult to climb.

Right now there are over 656,000 expiring domains that you can pre-bid on at Namejet. Lots of opportunity there even if more people come. The key is to find those hidden gems and wait until 1 minute before they go off the board (assuming no one has bid on it yet) and then bid. This is the best way to attempt to be the only bidder on a domain and win it for $69.
Length: This is pretty self-explanatory. Generally the shorter the domain name, the more valuable it is. This difference in value decreases exponentially as the name gets longer, though. For instance, the difference in price between 3 and 4 letter domains are significant, while the price difference between a 7 and 8 letter domain would usually be much less significant.
Domains are nonmaterial goods. When sold, the only transaction taking place is transfer of domain rights from one user to another. Barring any form of copyright or trademark violation, virtually any domain name can be bought or sold. Generic domain names, such as or, are not legally protected and can therefore theoretically be reserved by anyone.

Very good article and overview explanation. However I would not recommend buying names with bitcoin, ripple, etc in them. Not only will it be oversaturated those names are brands and can / will be trademarked and you can still be hit with a UDRP. Only register generic names like,,, etc. There are tons of opportunities and no need to infringe on a brand name.
It is much harder to sell names no one has heard of. Short names have the highest value — they are rare, easy to sell and bring substantial profit. Basic and common domain names, which can be relatable, or arouse interest in the market are the best. General names sell thick and fast and also bring considerably higher profit.  Names that are easy to spell will attract buyers, and provide good opportunity to make a decent profit. If you know you have a good domain in your hands, then you are likely to make good profit by selling it.
Check backlink profile: If you’re not familiar with what backlinks are, they’re basically any public website that “links” to the domain in question. Since there are numerous shady tactics in the SEO world, expired domains’ backlink profiles should be examined carefully. Check if too many links are coming from the same domain or if links have weird anchor texts/use foreign languages. You can use a tool such as ahrefs for these purposes.

That said, my recommended budget for beginners would be $500+. Using this budget you could buy a bunch of high-potential $10 domain names, expired/dropped domain names or a mix of both. It’s very important to invest only what you can afford to lose and treat this as a side hustle till you get the momentum going. As you gain experience, industry expertise and some sales under your belt, you can then consider slowly growing your business into a full-time gig.
