I use Golang since I need concurrency (to process websockets as fast is possible) and have to utilize all the CPUs cores with business-logic. A better choice could be C++, but "life is too short for C++"

Python is good when you start programming or need to implement and debug difficult algorithm etc. It's great when you want to write code fast, but not that good when you need high speed/performance.

As for learning, IMHO, you should learn Python and use official Python library for Binance. Trade by yourself and experiment with automatization. Then add more and more complex logic to your code.

And don't trust to any analytics (especially the ones that wish to make you rich) and don't take technical indicators too seriously.
