I got a suspicious looking wallet address

[pooya87]

Just for fun and to show you having human readable "words" in an address is meaningless... Here is a list of all bitcoin addresses with a balance that end in "dead" or any variation of the word (69 total):

Disappointingly enough none of them ended in "alive" but some do end in "live" (8 total):

Please note that I used an old snapshot of the list from 2023 that I already had on my disk (1.77 GB) thanks to LoyceV work here: https://bitcointalk.org/index.php?topic=5254914.0

A simple loop in C# to check for them:

Code:

private static string FindAddress(string filePath, string endString, out int count)
{
    StringBuilder sb = new();
    count = 0;
    foreach (var line in File.ReadLines(filePath))
    {
        if (line.EndsWith(endString, StringComparison.OrdinalIgnoreCase))
        {
            sb.AppendLine(line);
            count++;
        }
    }
    return sb.ToString();
}

Yeah, the list only contains funded addresses so, it might not be lucky enough to hit one.
The chance is low enough to make it significantly harder than 4 characters.
From 1 out of 58^4 to 1 out of 58^5.

Let's try all addresses ever used (this list is significantly longer than the list of addresses with a balance):

Using grep is much easier:

Code:

grep -i "alive$" file.txt

From 1 out of 58^4 to 1 out of 58^5.

Case insensitive, I think you'd end up with 4 out of 58^4 or 8 out of 58^5. Right?

Oh right, I've calculated the case-sensitive search, my bad.

You got the case-insensitive "ALiVE" search space right, it's much more complicated since three of the characters have two options (with upper and lower case)
And the two letters only have one each ("L" and "i" don't have other option).
