You can easily earn that amount if you have multiple ways of earning bitcoins as you cannot expect that income only from single source of income so try to multiply your ways of earning from sig campaign, trading, gambling etc.
That's the way of earning that amount per week and you shouldn't have enough time for doing it so. But I don't want to include gambling as your source of income, it may be good if you are an investor on a certain casino but for being a normal gambler, I don't that would help as it will always lead to losing a lot of money.
