Where do I start? So I heard about bitcoin and I know it’s all the craze nowadays. Let’s start from there. I’ll hop on Google Trends and type in “bitcoin”. Google Trends basically tracks the popularity of search queries over time, it’s often a goldmine for discovering currently exploding or soon-to-explode topics/terms..etc. So here’s what it looks like:

You can easily find domains using the best metrics available from Ahrefs, Moz, Majestic, SEMRush, Similar Web, SEMrush, Domain Scope and Social Networks. We buy only the best, the latest, and, the most comprehensive industry wide metrics so you have the maximum amount of information to make a decision. No other tool gives you access to 90+ metrics.
All very relevant points for anyone wanting to sell a domain name. Sometimes it is the basic points that we need to be reminded of in a transaction like this. What is the potential of selling a .com domain that has a relevant search term to a particular industry, but hasn’t been used on a website yet? So it is a good search term but no current traffic.

However, I'd argue that most people in the business really struggle as they don't understand what makes a good domain name and what's a bad domain name. While I do not work in this field full-time, I can say that I can make a living of it, but it's probably because I don't ask for absurd prices (e.g. randomword247.com domain name for $8000 is just unrealistic and won't happen) and therefore can sell domains easier. 
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 buycrypto.com, buyingcryptocurrency.com, theblockchain.com, etc. There are tons of opportunities and no need to infringe on a brand name.

This wonderful piece of information about buying expired domains is simply mind-blowing and I did not know about that before. It is easy for every one to understand about the topic with the pictorial representation. I feel sad that you lost around $400 due to Fake PR, but this article will surely help others save them from any sort of inconvenience.
What I like to do is sort by DP which stands for domain pop, and this is basically the number of linking root domains. So, BL is the number of back links. As you know that can be somewhat misleading if they have a lot of site wide links or multiple links from the same domain. I like to sort by domain pop. What that does is it brings up the sites with the most amount of referring domains.

Thanks for the great review on domain flipping. I could definitely see myself getting into domain flipping down the road. I constantly find myself thinking of domains that are probably worth buying. But the way you have presented and analyzed which keywords get the most page views makes it more like long term investing. I also never considered trying to market the domain names or that Adsense money could be generated. Thanks for sharing and good luck with your domains!

Yes! Selling domain is an emerging trade and no wonder if it can develop into an exchange. www.DomainX.org has been initiated with this view. There are some good ideas in the comments regarding which names to buy and how to grow their value. However one must not forget that it also involves a recurring cost (annual renewal) and keeping many of them might become difficult if you are not really selling at least a few to cover it. Enjoy free listing at DomainX.org.

Using the keyword search feature you’d also be able to familiarize yourself with how much domains typically cost on average in a certain industry or niche. Even better, they have an addictive little app called “The Domain Game” available for iOS and Android. They basically give you a domain and you try to guess whether it sold for three, four, five or six figures. You get points for each correct answer and lose points for incorrect ones. You do this for a while and you start to see patterns. Your brain starts connecting the dots and you get better it. Now you’re ready to go out there and scout some domains!
