I create my own crypto currencies with less expense. I spend money and time in marketing the currencies with a project. I bear the pain until the coin get its values. Once the coin gets its values yes the comes the profits. The first lot of vlaues they release may not bring much turn over, but once the value booms up and the coins created gets circulated, the profits just flows to the pockets. Besides it, need to look at various ways an ICO get its profits.
