As far as I can see you got mega flagged here:

https://steemit.com/introduceyourself/@crixtoveredwin/help

Because you used the introduceyourself tag, for a non self introduction post. Spamming inappropriate tags is a reason why people flag a post, if a user with large SP and high reputation flags you it can reduce your reputation number by ALOT. Like what happened to you.

Along the same lines, in this post you have used the tags, cryptocurrency and steem, of which this post is not related to at all. So the same thing could end up happening again.
