Now my problem is that when I try to transfer bitcoins to hardware wallet, I see a fee of 0.0005 bitcoins, what is the reason for the high fee? A few days ago, it seems that it was 1-2 dollars. Fee will not be reduced? If the fee is not reduced then I will withdraw with this fee.
Because its a standard fee for withdrawal on exchanges. Im not sure if theres an exchange lower than that but basically fees are incurred in trading and withdrawal on onchain crypto exchange. For that fee I think its fine already, cause theres no way you could lessen that unless the network is not congested and can process with a bare minimal fees.
