What an amazing coincidence!

I wish to create a system using new cryptocurrecies and bitcoin. I have 3 currencies lets call them a, b and c. We buy and sell each currency with bitcoin. I want to create a system where each currency is worth the same for example a,b,c are all worth 1 bitcoin, but they vary each hour for buy/sell opportunites say hour 1: a=1.05 b=1 c=.95 i need to know how it would work in a cycle of say 4-6 hours that repeats over and over again where everyone who trades can win and the owners of the coin wont lose. Keep in mind that the owner of the coin will have 1 billion of each coin and they are all worth around the price of bitcoin or $5000 each so running out is a long way away. Keep in mind that to participate a user must have bitcoin to buy from each currency and to take profits and cash out he must sell his currencies and transfer them back to bitcoin. Thanks

This is your incredible algorithm for generating infinite profits!?

As expected, complete nonsense.
