Dictionary.com defines the word "investment" as:
the investing of money or capital in order to gain profitable returns, as interest, income, or appreciation in value.
I'm not so sure I would qualify dumping money down the OTC/Pink Sheet toilet as making a "investment" but suit yourself.
I suppose if you changed the definition to:
the investing of money or capital in order to lose all of it in a scam; the act of enriching a sleazy crook who claims to be a CEO or CFO of a company that makes and produces nothing except billions of shares and lies; the belief that an evil cabal on Wall Street will enrich you; the belief that putting money into a worthless shell is better than working hard and contributing something to society other than baseless NSS conspiracy theories.
If this is your definition...well then good sir, "invest" away.
BTW, I know you don't touch OTC and Pink Sheet trash with some one else's 10 foot pole; I hope you appreciate my sarcasm.
