The concept of this project sounds very interesting but since BitWinEx is only buying back the coin when it reaches its peak price, how long does it take a coin to reach it's price and how does BitWinEx make it's profit from the tansaction?
When a coin is bought by a user, then its price automatically doubles for the next buyer. You can buy a coin at the next price without the permission of coin's current owner. A coin's price will only grow 5 times, up to a certain maximum price. As soon as the price of a coin reaches its maximum value, the coin stops trading, and its owner can sell it back to BitWinEx, receiving 10% net profit in the process. The BitWinEx Exchange makes money when it issues coins and sells them at the starting price.
