There are many ways to learn Bitcoin places like Udemy, Coursera you can still read the original Whitepaper by Satoshi Nakamoto, there various books and most of all sites like this (Bitcointalk) helps a lot too. Everything depends on your determination and your perseverance.

He shouldn't have assured you that you are going to gain profit from trading as a beginner, but he also did one good thing that he told you to read more about Bitcoin so that you can learn about it. Now, your first task should be to listen to the second thing he said; learn more about Bitcoin and this space as a whole, learn about trading practices once you learn about the basic things such as how cryptocurrencies work, how you can use wallets and exchange, and how you can make transactions, etc. Once you do that, you should move towards learning about trading practices.

I wouldn't recommend trading to you if you are a newbie, not at least in the first year or maybe about 6 to 8 months, and within that timeframe, you will have to be constantly active in learning so that you can have enough knowledge about this market. After that time passes, then if you feel that you are ready, then you can venture into trading.

You are right, learning from the Bitcoin whitepaper can be the easiest way to understand the concept behind f Bitcoin because all details are explained there and you will get all you want if you read and understand properly.

However, this forum is another safe place to learn about Bitcoin, you will get concise and accurate information about Bitcoin and crypto in general in this forum because this forum members are always ready to help people that are willing to embrace Bitcoin and they always share legit information about Bitcoin and cryptocurrency.

Nevertheless, learnmeabitcoin.com will give you well detailed explanations about how you can start your Bitcoin journey, and where to save your Bitcoin safely and the methods of sending and receiving Bitcoin.

Learn me a Bitcoin is a very good website for learning but it is generallly a website for technical learning. I know that it has two pages, one for beginners, and one for technical (advance) but in my opinion both beginners and advance are technical.

If people want something less likely technical too start, they can begin with https://www.lopp.net/bitcoin-information/bitcoin-explained.html

After understanding very basics of Bitcoin, they can learn more with learn me a Bitcoin website and this famous book.

The brother assured you of making gain when you start trading? Did you pay the person to teach you how to trade? Is it that the person is the one in charge of the account which you are using to trade? Or maybe the person is the one that’s providing trading signals for you?

If am introducing any newbie to trading, then I won’t be assuring them that they will be making money from trading, because I know beginners don’t make money from trading at the beginning, if you are learning to trade, then you will be losing money, and that’s why I do recommend beginners to always trade with just little amount of money, because they might end up losing most of the money that they start trading with. I don’t really think it’s right to assure a newbie they are going to be making money if they start trading. Before you start making money, then you will have lost some money during the learning process, and even as a professional trader, loss will definitely set in.

If there was ever a definitive way to this learning, we would have had several genius amongst us but, that ain’t the case. Learning doesn’t have no definite steps to it and you don’t need to learn in a particular way but, you need to pay more and close attention to whatever concerns cryptocurrency. Not just Bitcoin I mean but, how various networks and cryptocurrencies out there operate.

That way, you would broaden the scope of what you know and need to know about the cryptocurrency technology.

If you are trying to teach someone who is new to trading you can tell him that it takes time to learn and that they will can lose some money in beginning. You should tell beginners to only trade with small amount of money because it helps not lose too much while learning. And tell him sometimes people who are trading good can still lose money . Anyone who promises that someone will definitely make money especially when they are just starting should not be trusted easily. Good teacher focus on teaching them how trading works and how to manage risks and how to learn except promising quick profits. So always teach to anyone with whole details and tell everything which you know or refer to him to a trusted place.

First of all, before trading, you need to know about a specific coin and if the best coin on your list of choices is Bitcoin, then we should try to know as much as possible about this Bitcoin. Bitcoin is currently the most popular digital currency in the crypto market and the most valuable digital currency.
Although you cannot trust all the other coins in the market, you can definitely trust Bitcoin. Since Bitcoin came to the market, its popularity has gradually increased and people's trust in this coin has increased a lot.

Now if you want to do business with this coin, then I would say that the right decision to choose this coin for trading is another thing that you need to pay attention to in this case, in addition to knowing about Bitcoin, you also need to have sufficient knowledge about trading. You must know that trading is a risky business, so if you do not have a good idea about the market or if you cannot buy or sell at the right time, you can be damaged. 

So, to trade on the one hand, you need to have enough patience and a good understanding of the market. Hopefully, if you have an idea about all this, you will be able to move forward by trading with Bitcoin.

This is the perfect place for you to learn more about Bitcoin and with the help of many other people who have been here for a while you will be able to understand how Bitcoin is and the following steps to make you succeed, if you learn it all from a brother that introduced you to Bitcoin directly it will be very easy for you to understand, no one is perfect but since Bitcoin is introduced to you by your brother I think he should put you through the process and make you understand more before coming into the forum so that you can have more knowledge about Bitcoin before joining here.

What I’m trying to say is that learning about Bitcoin from someone close to you is better than learning it online, you can understand Bitcoin online but it will be different from learning it with someone you see each other will make it easy to understand, you can still understand more about Bitcoin online if you are good and grab some knowledge about it, the reason why I prefer you learn more from who introduced you to Bitcoin because that is the easiest way to learn about Bitcoin.
