Hashtag is a type of data tag that usually used in social media like twitter and other blogging sites. It allows you to find some related topics or contents with a simple hashtag. You can easily track some themes and some messages on different social platforms using #.
The advantage of this is to helps members to be able to look some information in a specific content with the use of it. It is very necessary for some new members that explores the forum. Widening some features in this forums level up the learning and knowledge about cryptocurrency. We all know that this is very common in social media only. Do you think is it possible to create this tool in here?
This forum is totally different from social media and i think hashtag is not required here. It might be used for promoting new ico's and services which could be another issue for this forum. Search option is also available on this forum so i don't favor the hashtag idea.
