Before learning to do crypto-currency trading it is best to learn about computer security, hacking and the whole inner part of a digital currency project on the go.
Learning the processes behind a cpu, gpu or graphics card helps you understand the crypto world and can save you from a bad investment.
Learning computer security will also help you recognize a shitcoin and a big coin more easily.
In Udemy you can find the following courses:
Informatica Tutorial: Beginner to Expert Level
Mastering Informatica PowerCenter 9
Informatica Tutorial - Informatica Online Training
Fundamentals of Business Intelligence & Data Analytics World
Other institutions such as the University of Toronto, Imperial London College or the Caltech Education Program can give you notions of computer science, calculations and more.
I hope you take this advice.
