const (
	// CuPriceDollarMonth CU price per month in dollar
	CuPriceDollarMonth = 10
	// SuPriceDollarMonth SU price per month in dollar
	SuPriceDollarMonth = 8

)

Price for 1 CU or SU for 1 month is 10$ TFT price is fixed at 0.05 CU and SU price per second is CU -> (10 / 0.15) / (3600 *24*30) = 257.2 SU -> (8 / 0.15) / (3600 *24*30) = 257.2

Variables
