as a domain investor, you probably cant.
thats why registries are the new domainers - they cut out the traditional domainer. thats where a lot of the attitude of people on this forum comes from... being pissed they cant register these for $8 and that the registry is charging $300/year..
so people compile lists and go HA! look! this registry only sold 2,000 registrations... hardy har har how pathetic. its only pathetic because the money isnt going in their pocket. like donuts.co registry for example... even selling 2 domains per TLD knocks out like what, 1/8th of their application fee of 185k! for 2 domains they get close to 25k! then take all the ones people register at $1,200, $700, $300 and even $150... it adds up pretty quick.
but as a domainer theres WAY WAY too many combinations to snatch up even if you were able to grab the super duper premium at $8/year... with this many combinations the hope of flipping them seems slim to me.
but people laughing at TLD's with "only" 5,000 registrations... ummm, duh. not sure what people expected with a bajillion niche extensions... it makes sense. a lot of these extensions wernt meant to have 500,000 registrations. its time to throw away the old calculator and enter the new realm of unknown.
