Justifiably, any attribute or factor that is known to be influencing prices, is doing so as it leads to demand. On how easy basis of such factor demand is raised and thus the price. Hence, these domains of media like segments as you say like http://www.hindi.media gain worth from the same factors that lead to demand. When price is enhanced or goes premium, the domains are thus known as premium domains.
Once you get to this point you know there have been DMAS listed. They have a number of domains linking to them and according to the way back machine which is WBY, you can see their site age. So, if you want to go with an older site you can see right here whether or not this is a site that you might be interested in, but before pulling the trigger you do want to check two things.
I remember the glory days of the Internet where people did make a ton of money buying domain names. Until I came across this post I actually didn't even realize that people actually still thought they could.make.a.lot of money by doing this. I have some domains that people would be interested in buying and I get contacted about them but mostly it is for people wanting to purchase them for like $1200. And for that price I would rather just hang on to the domain name. I also get contacted by a lot of people offering to sell me complimentary domain names at what I would call ridiculous premiums. The knew google is all about branding. I would consider paying for a domain name that has a great brand attached to it but I could care less about most keyword rich domain names. Of course there are always exceptions.
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.
