There is no such thing as a "successful" trader. There are traders who may go well one day and bad at another. Whoever claims for his/her error-less abilities he/she may as well claim the title of the bigger liar as well. I personally suck at trading. I must classify myself to the worst trader around; that's why I'm a perma-hodler ever since.
Well yeah, anyone who claims to never have been wrong is obviously FOS, but you can be wrong sometimes and still make profit. It's all about making more when you're right than you lose when you're wrong.
Thanks for the suggestions. Yep, TERA is a she. She was consistently bearish, but as I remember mostly right. It was a bearish year and no one wanted to hear it. As I recall she found trading bitcoin pretty stressful though.
AFAIK TERA never divulged their gender, and them being a she was based off of some sexist bullshit BJA came up with. Big shock there, I know.
