thank you very much, maybe it starts at 5 or L
I think it will probably take about 20 more attempts to get a correct key. If not, I will have negative thoughts.

maybe i changed the first 3 letters of the private key, it has it has 44 letters and numbers including uppercase and lowercase letters.
I also previously saved the private key 51 or 52 and do the same.
With your help, my spirit becomes better
thank all

yes maybe it starts at L or 5
but I still have some thoughts that bitcoin also has a private key that starts with 7
when I add about 20 times, I feel tired, scared, so I hope to be able to use about 10 or 20 different private keys at one time.
that's good for the user and can still be safe from other people's private key sniffers
thank all

Yes, and i want to ask for the private key starting with 7, will it be 51 or 52 characters
Thank you.

thank you very much
how many characters will be the private key if starting with 7 or 1, and if i enter the private key 44 characters in electrum is it ok?
i just remember it started as 5 or 7 or L
because i changed the first 2 letters, it's not K
can i import a 51 character and 44 character private key at electrum ?
is it difficult to convert from base64 to wif ?

thanks for helping
it starts is 7 or L or 5 or 1, it is 51 or 52 characters
that's all i remember
this is WIF ?
and if my private key have format to 44 character so where can I import.
I can add multiple lines at electrum to find the correct private key?

Hi all
My private key is changed 1 or 2 characters, and i compose about 100 lines on file txt, how can it be added automatically to know which key is correct instead of trying in turn.
