Tombola is an interesting project and a good concept. when is your project doing ICO and how much is the token supply?
1 TBL = 0.04508 USD
But I think when the project enters the stock exchanges, the price of TBL will start to grow. So long do not think))
Its better to start the ICO price to low rather than high value then after ICO it will goes down. Given this, investors will not be dismay when the price is available in the market.
