There will, believe it or not, come a time when the share price will stop increasing because everyone that wants it, up to a given price, will already have it. The only way to get someone else to buy is to get the share price up to a level that catches their interest. Further explained, folks that trade on exchanges such as NASDAQ, will not touch a stock that trades in penny land. Penny land is between .0001 and $4.99. Once everyone in penny land has their fill, there wouldn't be anyone left to sell your shares to. If you can't sell your shares, they become worthless. I hope this helps.
Don't get me wrong, I dislike R/S's for any reason.
