... but I'm still not sure how to export the BTC private key into the BSV wallet.
what BTC wallet do you use? different wallet has slightly different technique to
export private key
If someone could elaborate on the difference between exporting and sweeping private keys that would be helpful. Thanks.
perhaps you mean difference between
importing and
sweeping private keys
importing is adding an address-privkey pair to a wallet
sweeping is transferring funds to an existing wallet address
~ I will be transferring the BSV out of the ElectrumSV wallet immediately if I am fortunate enough to gain access to my funds again.
if that's your intention, I suggest you to import it first then create a transaction out
during new wallet creation, select
“Import bitcoin addresses or private keys” option
then paste your private key
(the one exported from your btc wallet)
