I am interested in learning how to code, but for me it's a large topic.
I want to code for example for:
- Being able to reproduce what is inside the book "Mastering Bitcoin"
https://www.amazon.fr/Mastering-Bitcoin-Andreas-M-Antonopoulos/dp/1449374042 - I also want to be able to create a wallet where it changes from a 2-3 multisig to single signature after x months
- I also work in Finance and SQL is required, that's why I want to master this too.
Where should I start ? Any advice ?
I suggest learning to code without any particular application in mind at first. Start out with a language that is easy to learn and widely used such as Python or Javascript.
There are many sites that teach coding. I don't have any recommendations, but try
https://www.codecademy.com/.
While mastering the basics, you might try to write applications that can create and process SQL queries or interact with financial APIs.
