I have DASHCOIN QT WALLET. I have 2.5 dashcoins in it. I am using this wallet since 2018. Recently after Pc format I restored it on new PC. I am trying to send coins to my exchange wallet and it always say " Invalid receiptnt address". I tried diffeent dashcoin address but its same for all addresses. This wallet is not syncing how much I try. Is the send issue because my wallet is not synced?
