That's not always the case - they are rare but there are some very good newsletters out there that are long term focus - look at CAVR, 3 months awareness campaign and holding steady to 400% gains, same one also did DEGH and holding strong up 1,000%+ - I usually follow these guys and now with a new pick coming out today I look forward to it.
I have been holding COBI since it started and currently down, just hoping to see if this can bounce.
