I guess we all went through being newbies. Often in the beginning we even thought it would be the worst until the end because we are just new.
At first you need to gain information of what is really trading all about.. like... find out each of its contents and how in the end you will not make a mistake that you will regret a lot
Trading is a central economic concept that includes buying and selling assets. Frequently in trading, dealers attempt to exploit market volatility.
To start, of course, you need capital to trade with. If you don’t have savings and start trading with money you can’t lose, it can have a seriously detrimental impact on your life. 
Trading isn’t an easy feat - an overwhelming majority of beginner traders lose money. You’ll need to expect that the money you put aside for trading can vanish quickly, and you may never recover your losses. So you should start with the amount you can really risk.
Especially if you have an exchange that you have already chosen.. For example, in kucoin .. you can trade various coins like BTC, ETH and XRP and many more.
