Its very common and ever since before there's a lot of people claiming there selves as an expert so that's why everytime i saw some prediction around in the internet i never fell and always make research instead to figure it out the real situation.. To good to be true. 
a lot of predictions published and as if they were professionals. but in fact no one knows for sure the truth of that prediction. therefore predictions from ourselves that must be our guide in moving, of course, do not rule out the predictions of others, we can only make comparisons with our personal analysis. many signals circulating from free to paid, but in the end no one is justified in their predictionsand besides we are free from predicting or listening , but best to never rely completely from those because it is our money , and we will lose everything from small mistakes if we will not do our own researching .
