One of the things that happens, can happen, & will happen is mistaken IDN registrations.
A lot of times we see what see like prime terms being sold for cheap in various languages.

For example you will see something like

“Cheap Hotels” in Russian or other languages.
You buy it, hold it for a few years then show the first Russian friend you have that comes over your house.
Only to find out there are 3 other terms better than yours or worse yet it’s a common misspelling.
I’ve bought at least two of these & others have two.

This is one thing that keeps many investors out of the IDN market.
I have lots of domains so all my regs are good is not enough.
One question that should be asked up front by buyers is
“Is this the main term?”
I don’t think that I asked that for my nonJapanese purchases years ago.
Only recently looking through my portfolio did I notice this.

Since I am only a bystander in the IDN market. I like to look at it from a unbiased standpoint.
Only info I can give is for the market of Japan where I am an advertising professional.

Good luck & happy hunting.
