We should only be required to be able to manage and manage finances and how to find the right consumer.
Someone may ask why, and the answer is incredibly easy.
You can literally just start a new business, even without a big investments! You dont have to register any company because you work alone with your own money.
Take a look for that: let's say you have 2 bitcoins.
You can diversify that amount on many kind of investments, put up 0.5 btc in the most known and trusted bitcoin casinos.
After that, put up 0.5 bitcoin on loaning purposes (for example on polo,they provide great rates) so you have 1 more bitcoin. You can use also 0.5 for loaning too, but this time on the bitcointalk.
You still got 50 milion satoshi right? How about using that for trading? If you are not into it, then there is also a possibility to just hold it, for profits!
