No matter what anyone says, the bottom line is that you will make the most profit with the crappiest letters possible.
"Crappy letter" LLL.coms went from 4k to 8k in 1 year
"Good letter" LLL.coms went from 12-14k to 18k in 1 year
you tell me which was the better ROI
If you can get a LLL.com for 5K jump on it and ignore my previous advice
But always conduct due diligence, research the domain history, make sure the name is clean and you're not dealing with a scammer.
