Dont rush things and take time learning, thats your key to become a pro trader and become succesful.
Its like that, word safe and trading cant go together in the same sentence. When you think of trading, any kind of trading, it has some risks, depending on choice of coins, your bankroll, planned profit, risks can be low or they can be very high.
I think there's only one way for people to start learning about trading, decide to spend some money and don't regret it. Use that initial capital that you can afford to lose, first trades are learning, you will spend some money, but you will learn about transactions, sending fees same as trading fees. To learn all that you will spend some money, and if you think you can do it try it with more money.
