but what about the chips, will they be coins or just something like shares simply tied to specific addresses of IBCO participants, on which dividends are accrued as a percentage of the participant's amount?
Chips are the BTC someone is going to invest. For example, 1 chip = 1 mBTC. In return, investors will get 10% of the monthly revenue from the site. If total revenue is $1000/month, then investors will receive $100 and this will be distributed among all the investors in term of their investment percentage. And they will be paid in form of BTC in the same address they will send the chip (BTC) from.
