After searching various online platforms youtube twitter different places I realized that if I want to do cryptocurrency trading it is very important for me to learn many things first including -

• Technical analysis
• Fundamental analysis
• Candle Analysis

of course technical analysis, fundamental analysis, news about positive/negative factors what's happening into the internet. BULL/BEAR trends. DYOR before buying. Don't be greedy by making profit for a while, do a multiple work so can invest and build much better portfolio and do not depend on trading only it is good for earning for a certain boundaries but don't make trading as a career.

Do you know of any platform or site from where I can take professional trader training?

No one is perfect and absolute always earns. You can learn in youtube, google bla.bla.bla  meanwhile selflearning from TA, FA  visiting news sites may helps you building your strengths. So, keep grinding it.
