I understood from your web site:

You find a way to sending  fiat money back from Korea
You have been doing it for 2 years.
You need more money to increase the fund.

So, is your coin (Wonarb account) or ICO represented a share in your fund ? or it is backed up by something.

What gives us assurance about our bitcoins in the fund?

My only regret is why I did not care about it and search one year earlier than this.
I was only wondering why people pay money for a coin created with computers. Why people give value to it. I learnt all the answers but it became late for me.
