Do I have to pay a gas price if I send ether from account a to account b in Ethereum MainNet?? Or the transaction is free of cost?'
And if I buy ether from Changelly the destination address have to pay something extra?? Or I get the "clean" quantity of the value that I buy in the addres. For example , If I buy 50€ in ether are going to receive 0.26670439eth??
