The price for the software is $100. Payment can be made in Bitcoin (Bitcoin Address: bc1qakhl8eu20ely220fxm6d3tjsk2al64vrha4sxa), Ethereum (ETH Address: 0x22D2C1C38b3c26C9E403B34ea5aF42Af00e90d9f), Binance Coin (BNB Address: bnb17CqMQFeuB3NTzJ2X28tfRmWaPyPQgvoHV0205gfc6ykk), or through PayPal (Burner Account: [email protected]).
