SBDomains if we buy your coin from an exchange like novaexchange will we be able to withdraw the coins to the wallet?
And what happens if we format the pc or change of PC? Is there any way to back it up online? (The wallet or the address)
Yes, I tried withdrawing from Novaexchange to wallet - it worked fine.
You need to create a backup of the "wallet.dat" file. Open your wallet and find the option in "file" and save it somewhere else like in a usb pendrive or something..
