Comfortable? Relatively, yes. Some penny stocks follow through on PR's and grow. Some penny stock CEO's are legit, just running a Jr. company. Not all penny stocks stay penny stocks. Some are in the infantile stage and use the funding capacity of the market to create, fabricate and create earnings. KMAG has earnings and this month you'll get to see a greater vision of what they are becoming.
You are greatly mistaken by lumping them all together as exactly alike. They are all very different. KMAG is different.
