From the which extension u have made the the highest profit.

For me the extention with the highest profit is .info. Maybe becuase its so cheap to register and there is less risk.

.com is always the best, that will never change.

Developing any .info domain has been a great experience for me but for domain sale, .com is best

.com has always been the best for me.

I would’ve loved to have 100 LLL.com as they are worth a fortune in todays market!
