hey pennypal - you got it backwards
you earn money from job, save, then buy stocks that have positive cash flow & earnings (even if it's just 1 or 5 shares) like Google or Ulta Salon (ULTA)
then when you have $100 or $200 profit (folks need to better learn about respecting hard earned money - as this could take 1-3yrs say for a good growth company, $200 a share or whatever, to double) - then you can take that $100-$200 and gamble in some penny stock
then when you witness how fast that $100 or $200 disappears in these penny scams
you will hardly ever do that again with capital that took so long to make
