As you all may know, Global ICO Insurance System has included DateCoin into its reimbursement programme.

This is what we are going to do: we will take the price that was present at the time of the ICO for which investors bought the tokens and the current price on major exchanges where the tokens are listed. The difference between these prices will be available for all tokenholders on their trading accounts. Good luck!
