May I ask what your "business idea" is ?
I am still developing my ideas, so it would be unwise to try and describe my embryonic concepts now and risk being misinterpreted.
I would say that to me POS coins on a crypto 2 platform like NXT & NEM resemble virtual real estate, but unlike physical real estate, POS 'real estate' on a crypto 2 network can move around.
For some ideas you need a lot of 'real estate'. A block of flats, a shopping mall, a hotel, a fun park, a casino etc
Imagine if virtual real estate could relocate to anywhere on the network at zero cost in an instant.
6-10% of a POS coin is enough 'real estate' to create many 'things' that can't be created with 0.0003%
I know I have not explained anything, but it is some thoughts.
