I OWNED DOMPERIGNON.ORG, incredible, but true.  Lost it, back in the days when internet in India was not a readily accessible utility. And I was a casual domainer.  You had to go to a cybercafe. Did that late in the day, towards the expiry of the domain. No chance of renewal. The domain is now with the owners of Dom Perignon and is redirected to domperignon.com! 
Many people think of domain buying and selling to be one of the easiest methods of making quick money. Perhaps, you may have heard of someone buying a domain name for under $3000 and then selling it for $25,000. A quick $22,000 profit! Such stories can be very motivating! And that sort of money does exchange hands (Go through 10 of the biggest domain name sales of all time!). But these deals don’t come as easy as they seem! Ask anyone who flips domains for a living and he/she’ll tell you the amount of hard work and skill that goes into it.
What if we replace “bitcoin” with “ripple” in all these examples? SellRipple.com? RippleGiftCards.com? Ripple.network? Ripple.us…etc. You get the picture. There are a 100 of these on NameBio + the keywords we got from the Google Keyword Planner, that’s hundreds of potential high-value domains right there. The thing is, we’re only scratching the surface here. According to Wikipedia, there are over 1,300 cryptocurrencies online as of January 2018.
So what are some strategies to finding great domains to flip?  Well, the first is to find quality domains.  There are some sights that publish a daily list of good upcoming Namejet auctions like here: http://www.tld.org .  This is an easy way without having to search to find some great upcoming auctions to bid on.  If you have the time you can search Namejet yourself.  The key is to making money by flipping domains is to find domains that other people will want.  If the 30 day window period just started on a domain (for this example let’s say it was Anticareer.com) you could use Google to search for ‘anticareer’ and ‘anti career’ and see if you can find people who own sites that may be interested in this domain.  Email them and ask them if they’d have an interest in purchasing the domain Anticareer.com.  If you get some bites you can then go and bid on the domain and if you win it you can flip it right away.  Once you get some experience it will be easy for you to spot the domain names which you can quickly and easily flip and you’ll also develop a good feel for what price you should pay to make yourself the amount of profit you want to make.
There’s an important distinction to make here between domain flipping and website flipping. The latter mainly refers to buying and selling full websites. By full websites, I mean websites that actually have content and more often than not have traffic and revenue. When buying and selling websites, the domain name matters less as the main value there is the content, traffic, revenue, history/reputation, sustainability and growth opportunities. The same can’t be said for domain names where you’re just selling “the name” and hence it’s all that really matters.
