Thank you! So complicated... lol. When I do a dumpprivkey on bitcoin, I'm getting a very different type of number L2NLwmubxxxxxdMsHxxxxxxxxxxxxxxxxxx
It's easier if you stay in the hexadecimal and use tools:
f9001 + f8c = f9f8d (one can do this without a calculator)
and then:
$ ./bitcoin-tool --output-format base58check --public-key-compression uncompressed --network bitcoin --input-type private-key --input-format hex --output-type private-key-wif --input
