In btc core I only see defaultkey for the moment I was in 0.18 , for see receiving adresse I need to generate them in 0.12 then ?
Aswel when I loaded up another wallet I found error in btc core telling me ss13 , like my ecdsa ss13 this is something in collaboration with asii. But this things is different.
I need to generate these adresse in 0.12 for the wallet with coinbase coin ? How can I generate 60 000 adresse in btc core at once ?
Then try to obtain your private keys with command salvagewallet or dumpwallet and import it to another Bitcoin wallet (e.g. Electrum)
