You don't have to be the best trader to start trading. Right?
You have to know how to trade and where to trade. I am not talking about bot trading here. I don't suggest bot trading as it won't help you to learn trades. I do not agree that you must lose your money to learn to trade, and it will teach you the best lesson. If you are a billionaire, that's a different case. But, On an online platform, You shouldn't suggest such things.
Surely demo balance and demo trades help newbies how to do it. Even some casinos offer demo tokens to test their games. Some of them offer faucets for their games. Did you see when a new medicine invent, researchers never test them on a human at the beginning? They try it on other animals first. You don't have to lose to learn something. I respect your opinion. But, I don't agree with you.
Of course you are right, it is much better to learn in a training version of an exchange, but how many people will do so? Maybe couple of hours or days and it is definitely not enough to be experienced trader but then they'll anyway start trading at a real market, in majority. So IMO we should not only give advice for in case of an ideal situation, but for as they'll more likely will do. And IMO it is good to say them to use not more money for trading than they are ready to spend on entertainment, because they'll lose their deposit in 99,9% cases very soon. And even after that a majority of them will hardly use a a training version for long enough.
Sometimes we don't have to say or suggest everything to others. Even though we know that they will try the demo mode for a couple of hours only and then leave it. They will start trading with real money. But as wise people, we shouldn't suggest they start trading with real money on Day 1. When will they be veterans at some point and understand everything, they will there was a guy named joker10. He suggested start trading with real money even though there was a option to learn in demo modes. I believe you don't want to find yourself there.
Sometimes we know that scammers like 1xcrap won't stop doing their shitty business. Doesn't mean we won't ask them to stop or we won't ask signature participants to not promote them. Whoever want to promote them, they will do it even if they get tagged or whatever you do to them. They will continue.
No matter if they use the training version or not. You can always suggest them to try training mode with demo balance before they start trading with real money.
