I do that in an hour easily.
You are an expert gambler, and you've got a big winning history. Not everyone has got the patience to gamble as you do. I've done it in the past through Dice, and the same got ruined on the same day. It's not about the greed, but the lack of self-control. I started to gamble at midnight and reached $10k+ in the early morning. While having breakfast, my wallet is empty. This is a possible thing, because there is one year, and all we need is the perfect plan and patience to handle the bets.
Lots of depends on the player and his strategy. It is possible to win fast but it is difficult to avoid gambling the rest year. The same time it is difficult to make 3-5 bets per week with small risk and small win. Every week.
It is easy enough goal but not for common gambler. The same time - you don`t get any prize for reaching the goal, so you want to increase the prize. As the result it increase the risk of losing.
That's true, though it's difficult to control your emotion when you are already inside and already enjoying your sessions maybe there are some who can manage but most likely gamblers wanted to take a shortcut, big risk with big earnings instead of staying with your strategy and patiently waiting with small target.
It's tough but doable if you have that good balance on both money and the time that you'll going to spent with strategy that you'll going to follow.
