Instagram is reputed for image only. For your gambling casinos I think it will be better if you can create/open Facebook page and/or twitter profile then users of you can get update of you easily. Hope you have understand and you will create Facebook page as well as twitter profile.
In order to get more gamblers on your site, it is recommended to target each and every social media platform. A successful business / gambling site should have presence on FB, Instagram, twitter, telegram etc. In order to gain quick popularity, you may start with a social media campaign for the gambling site also (although i have never seen a social media campaign for casino maybe because no one has thought out of the box).
Thank you a lot for your advice! We were actually thinking about going on other social platform, we've just decided to start with these two (Telegram and Instagram). We would still recommend you to follow us there, too, as we will announce special promos for social platforms.
Can you please give link to your telegram and instagram so that we can follow them and get first hand information about the special promos.
In addition to this, i would further ask you to start the signature campaign on this forum. Almost all of the good casino have long term campaign here and if you can also run a campaign, it may give big boost to your business.
