I do have a serious question for the knowledgeabl

I do have a serious question for the knowledgeable investors here:

I see quite a few people saying they have millions of shares, I personally have 790k, i purposefully have kept it under a million and have set my sells incrementally in small blocks starting at .10 all the way up to a dollar with a minor amount of shares left over to satisfy my "TO DA MOON" curiosity.

My question is, and remember, im new to trading so i have never seen what happens when a stock catches on fire, How are these multi-million share holders going to dump back into the market and not kill the momentum? Hopefully this is not a silly question?

Have a great weekend fellow BMSN'ers!
