I have done this many times...Most have worked out and some have not.It's a gamble but it only takes one out of 10 to hit.Here are a couple of example's I bought 2500 shares of Silvercorp metals at .50 cents still own them today.I bought 5000 shares of Gogold resources at .16 cents still own them today.There are to many to list that i made a killing on.Also many that went to zero.But over all i am up almost 6 figure's..
