I trade a lot before but not such big amounts. For me 20k are a lot of money.
Usually just like hobby start with 50 euros and in a month easily 200-300. Never lost. But my target was low everytime
I try 75% back at least.
If you were able to quadruple your money reliably in a month and 'never lost' then you'd be a millionaire in less than a year, and 20k would be chump change. Time to stop exaggerating your prowess, delusion is your enemy in this game.
