Won't solve the issue.
Don't know but your previous speed doesn't sound right for an old i3 CPU from 2012 (
third-gen maybe) when searching for '1*'.
You'll likely get 1000-2000 per update of "
Found" at best (
based from my PC w/ i3-4130 procie).
Other than the additional
-c which is unnecessary for a wildcard prefix, I can't find any issues with the command you're using.
If you previously used an older version with faster result, then downgrade to that.
Also, might the "1*" be the problem? I don't necessarily want it to generate prefixed addresses.
I want it to generate any random addresses, no matter the prefix.
Also, the 'readme' seems to be misleading, '*' when used will generate the prefix at the end of the address,
example:
vanitysearch 1*abc will generate addresses with 'abc' as the last three characters.
But it's written there as:
(Can contains wildcard '?' or '*')
Perhaps it's not intended to be used as a wildcard.
You can report it to the Github:
