As you managed to post such a generic comment in the first minute after the post has been published, I suspect you might be a bot.
As well, as you didn't even upvote the post for which you are saying it's "nice," I also suspect you might be just fishing upvotes and attention.

However, whoever and whatever you are, but seeing that your account is very new one, I would strongly suggest you learning first the Steemit Community rules as such meaningless and generic comments that (as I could see) you are leaving around on other users' posts too, may only bring you more trouble than any gain.

Therefore, I'm leaving you here the link to Steemit Etiquette Guide which might be a good start to educate yourself what is acceptable on Steemit and what is not.
