Hi, I've heard about Bitcoin for ages now and I understand the massive potential it has. I'd like to say I understand its features such as the blockchain technology and the ability to mine more, but I must admit I have much to learn.

My question is in the title. It may sound really stupid and I know that there certainly is a way to prevent someone giving themselves more bitcoin, but let's say I have a cold wallet with 1 bitcoin on it. Could someone somehow change the code in a way and make it into 2 bitcoin? Like to me it just seems like a number that represents the number of bitcoin you have.

Thank you for bearing with my stupid question, but it's been bugging me for a bit.

If hackers was able to gain control maybe at least half of the mining process of a certain block, from what I've read, they can form those included transaction and create forks which real tx aren't reflected, through that they can double spend bitcoin.
