I understand how you feel, because this was how I felt too.
I once invested in Forex without the Investor's Sharingan, and lost not only my money, but also my parents money.
Then I investd in crypto currency without the Investor's Sharingan, and not only did I lose money, but also lost the opportunity to gain huge profits on its sky-rocketed growth. But since I've learned how to use the Investor's Shargin, I have not only made huge profits, but also totally avoided a lot dynamite investment.
