Since your account is new I will assume you are new to domaining as well.
The fact that you don't understand why this domain is not good also points to the possibility that you are a newbie.
Please don't be offended by our appraisal of your domain name.
It is not done to be malicious.
Many of us who are commenting on your domain have been at this for quite a while.
We usually suggest that newbies study for a while before making domain name purchases.
This is a good idea so you will not lose a lot of money investing in bad names.
If it makes you feel better we all went through this phase and were where you are now.
You will get better at this.
Dot IO names are better if they are single word names, and only certain types of names sell.
Check NameBio to see what I mean.
Even as a dot com this name would not be good.
As a disclaimer, I always say this is a crazy business and bad names do sometimes sell.
But don't count on it.
