I think few people have followed the link provided by the OP and read the entire article. It contains many interesting facts that reveal the identity of another unsuccessful trader. One of these is that at the end of May, Wynn lost almost $100 million in liquidations. And the longs he opened with a leverage of x50 brought him a profit of more than $ 10 million in March.
Weak minds tend to be corrupted by success. In the case of Wynn, he thought that he had a gift or skills after he made big money. Once the success gets to your ego, everything goes downhill from that. This is the opposite of how you should behave. If you manage to win big, take the win humbly and thank providence for your luck. Afterwards, never engage in any risky behavior of any kind. Trading, gambling, and such things. This is how you maintain your wealth and improve yourself.
