Let them think like that because they will know that if they are right or not. To make a profit from trading is not easy, and they need to learn more and more about trading so they will have a chance to get the profit. But if somehow, they can get the profit from their first-time trade, then I will call them as the luckiest person because not all new trader can make their first profit in the first time. I think they don't need to use big money to trade because they need to make them familiar with the situations in the market so they can trade without a problem. And after they can familiar with the trading, they can use big money to continue trading.
Besides that, they will think that trading is easy because they can get their first-time profit. But if they don't learn more about analysis, they cannot make a profit again in the next trade because the situations will not be the same as before. There is no way for us to make a profit in trading if we don't have the skills to analyze. That is why even traders can analyze with easy, and they need to still learn to trade because no one knows what will happen in the next days.
