Better to do not do it, we dont need any scammy coin or crappy coin, it is obvious that you are going to develop something in order to scam everyone, i dont even need to read your post history in order to discover that.
I can have problems if I copy any code that is from another person or that I find by there to create a cryptocurrency or create a token for example an erc20 contract of ethereum?
No one is going to give you a code for free, or at least, if you are not a developer or if you do not have any knowledge about how to code, you are not going to be able to do anything.
Better to put some effort & money and try to hire a good developer for doing it for you.
But if you copy a code, nothing is going to happen to you because those codes are mostly in github
