  2. Hello

    I saw in your video number 27 you showed how to give a newly generated coin value.
    A few years ago I did a treasure hunt mining process. I have seen newly generated coins show up in my wallet. I have been unable to process them and was unsure of any value. Your explanation seems like it is what I need to do to give the coin value.

    I down loaded python 3.5.3 and node.js 8.93 and installed the bitcoin lib along with the other installs on your site for the node install. I’m getting error messages when I try to do the same thing you did. I used your example as a practice. I'm unsure of my python skills. I need an easy way to do this.

    When I look at a transaction from an address in my wallet the scripts are different from what you explained. I read something which said in a coinbase coin there will be no scriptsig. Would you know which scripts to use in the Hexadecimal value? I have included a transaction numbers below the values seem confusing. Would you know how to and what values to use to process the coins.
