OP I would first warn you to tread carefully on the trading platform. Trading platform is one such platform where you cannot do anything easily. Of course there is risk to be taken in this business. You will never make money from a trading platform unless you dare to take risks. I would say first of all you have to take risks.

Yes beginners should never trade with large amount of money to trade. If they accidentally make a mistake, they lose all their money. For this they should trade with small amounts of money in the first instance. Even if it is lost in the learned state, there should be no regret.
I would recommend to the OP not to trade. He doesn't explain much but he looks like a guy who wants to get into trading because he wants to make easy money, when it's very difficult, there are very few who make money consistently and it requires knowledge and dedication that he doesn't seem to have.
I would rather take advantage of the forum to acquire general information about bitcoin, and consider whether to invest for the long term. If he decides to trade in the end anyway, let it be with more knowledge than he seems to have.
