He can trade but he will be more likely to lose all his savings, not only in trading but in all types of work, business and others if done without the right knowledge you will get nothing but loss and despair, even when the person has the knowledge and is ready plunging into trading he still has the opportunity to lose because not everyone is suitable for trading. Sometimes it's easier to start a business in the real world than do trading.
Exactly true that knowledge is the power and if you use knowledge in a right way so there is nothing more difficult to achieve. Business in real estate is more beneficial because than trading because trading needs learning and if you learn then use your knowledge accurately also matters as well as to learn how to take step during difficult circumstances. Business in real estate is not such risky as that of the trading but people prefer trading more because of its high return but I think never have to put your overall money and as you have profit so use profit for trading and recover your invested money back for further use.
Doing something without knowledge is like creating a time bomb that will explode at any moment. Especially in terms of trading, someone who has a lot of experience and knowledge can still sometimes be wrong in analyzing the market, especially this who acts without knowledge, I prefer to say it as a gambler, because what is the difference because surely those who do it hope for luck alone, while something that is very thick with luck is gambling.
I would say no to someone who has not enough knowledge to do trading, it is better to invest in bitcoin alone while learning more about how to trade, and what we have to understand in it.
