If you care about the aesthetic matter of your post, yes. Stuffing hashtags at the end of captions is unpleasant. You can link the hashtag between sentences on your captions so it looks neat and appealing. Also, you can ‘hide’ the hashtags in the comment section so people will not see them while you still promoting your content with hashtags. But, remember to comment on the hashtags quickly after posting. Instagram promotes content based on when it was posted. If you are late, your content may not be added to the suggested pages.
