Twitter is an easy to work but hard to apply especially when your advertising tokens or coins. First thing, does this 100 followers a re all actually bitcoin users? If not then tahts the reason why theres no one messaging you regarding with your promos and stuff. Second, maybe twitter users didnt think your credible enough sinece you just have 100 followers on twitter. You may think its a little overboard since they only think that your not credible enough to believe in. I advise you to empower your account over time and use hashtags that is suitable with your current Promotions.
