    .DESCRIPTION
        Calculate the number of days to brute force a keyspace with BitCrack given an amount of keys per second "mkeys".
    .PARAMETER startingexponent
        Starting keyspace
    .PARAMETER endingexponent
        Ending keyspace
    .PARAMETER mkeys
        Millions of keys per second
    .PARAMETER shares
        Number of shares keyspace is split into

Tested but got errors:
./Calculate-BitcoinKeySpaceBrute -startingexponent 40000000000000000 -endingexponent 7ffffffffffffffff -mkeys 60 -shares 1
Errors:
./Calculate-BitcoinKeySpaceBrute: line 1: syntax error near unexpected token `('

./Calculate-BitcoinKeySpaceBrute: line 1: `Function Calculate-BitcoinKeySpaceBrute() {'

Here ya go!

Thanks for response!
I'm on Ubuntu. Extract the file and chmod the file 'Calculate-BitcoinKeySpaceBrute'.
Try as you do but got the same error.
Your first command Import-Module... is return: command not found.
Normally that's because you are using windows.
Any ideas?

This is a PowerShell script. Either use it on Windows or install PowerShell for Linux. On your own now!

Got it! Thanks for help and share!
