as i am a newbie.. i know nothing about trading... what should i do to start trading and multiply my btc.. guys please help me
If you know nothing about trading, don't trade.
You will have to spend a few months, at least, to learn the basics of it. With a very small investment, it can be useful for practice. However, to earn enough for a living, I'm afraid a very small amount will not be enough. You would need a few tens of thousands of dollars for that.
The market is full of people who knows nothing about blockchain and crypto but tries to trade anything they can hear from their friends. This is pitty, please avoid this and learn on your own, or leave trading.
