For me this is complete nonsense. Risking 10 to 1 means you need to be right +90% of your trades to make money, because in 1 trade you can lose 10 times more than you can win. That's indeed insane. Look up the definition of INSANE and you will understand that in short time things will go wrong. Because you do things that are insane.
If you trade with insane risks you will never survive even 2 years. Insane means a risk that is completely out of proportion. The first thing a good trader has to do is watch the risk/reward ratio. If you risk 10 to win 1 it means you watch the ratio upside down.
I know somebody personally who took insane risks. Started with 1 million, doubled it in 1 year, and lost in the next year TEN MILLION. He even did not survive the full second year. He lost everything he had, including his businesses. His wife left him too. But that might have been a positive thing.
That is nothing
Look up Sean Quinn Irish Billionaire, his net worth around 2005 was something like 4.2 billion Euro, after starting out with one cement lorry back in the late 70's I think, and by 2007 had his hands in many pots, covering bottling plants, food processing, cement mixing, health insurance, life and car insurance, and many property investments across Europe.
He started to buy shares in Anglo Irish Bank round 2005, using leveraged CFD's, on advice from his "professional advisors", and by mid 2008, roughly, he had lost 4 billion Euro as the worldwide property bubble bust.
So, a person can make heaps of money for most of his/her life, and still blow it all with one silly decision!
I remember seeing a programme they done about him during the boom, and he was a very quiet and private man, set in his old ways, and would not even carry a mobile phone, which he is obviously very sorry he did not do now, as one simple phone call could have saved him, literally, a fortune!
