A Word of Warning, page-29

All speccie are high risk. Your experience is typical. We gain some, we lose some. Why do people still invest in speculative stocks? Because of the high reward. any past losses can be used to reduce significant tax on future gains, so effectively you only lost half of your $140k (viewed this way, losses are more palatable) it’s not the end of your investing world if you can pick a few winners. Instead of me warning you, just keep trying until you succeed
