It's good to see they finally answered your questions but they also took away the fun you had humouring yourself...
To me, buying NuBits is not such a bad idea cus it seems it will stand the test of time.. yea, the turn out may be small but it's not that bad.. a proverb in my place interpretated in English says that 'small drops of water, later fills the drum'.... So NuBits may give out small 'drops' of percentage each month but it will surely fill the 'drum'
