If you have the money to speculate or gamble with then do so, but the adages that apply are;

"Never gamble more than you can afford to lose"!
and
"You need to shift a lot of rock to find the nugget"!

International domain names are significant only to express ones identity or brand in your own language. Hence, for practical reasons, it is not really worth buying unless the unique expression of brand highly matters in your case. I hope this helps.

If you just want a domain as an investment and not to develop pretty much only .com with no - dashes will do. People will not buy anything else for significant money. But if you wish to develop a domain from scratch those are not the domains that you should look at.

An idn has extra pull in the country or region it is registered in. It can still rank in global searches but it has no advantage over .com, .net or .org and possibly a slight hindrance.

So it all depends as they say

IDN enables you to have a domain name expressed in the same language as your non-english website.
