Do you mean to say $40,000? That's a big amount to win in just one night, I wonder why did you keep on playing instead of cashed it out (at least half of it if you want to keep playing). You must be a whale who thinks that $40k is just a small amount of money so you keep playing in order to get more and more money or probably you did not even have a target when you are gambling so you did not stop while you had very nice profit.
In just a night, you grew from 1k to 40k and yet didn’t deem it fit to withdraw immediately, you keep on believing in miracles of growing to 100 but that is greed and lack of self control. Anyway now that he is back to square one, he has learnt in the hard way and its quite painful. I really hope he has gathered a lot of lessons from this. I have never win huge money and the day I win, I plan to withdraw it without ever having a second thought.
