These days it only cost you 19 BTC per week. But you have to be very active. A min. of 60 minutes to an hour per week.
If you can do that, potentially you can become a very wealthy man, if you've got 60 minutes to an hour per week of free time.

Are you serious?
How can an hour work per week assumed as very active? With that 19
BTC you even could hire a bank manager for a week.
