I learn trading myself and I understand what it is, the trading site guides and videos were even enough for me to learn how to trade. I did not use demo, after reading the article and videos that the trading site provided, I deposited small amount of money and used $11 to trade and the experience began that time.
You sound like exactly how a newbie should get begins with cryptocurrency trading but basically I am not against to demo account. I mean I will suggest to engage in demo accounts for time being rather than learning such things from articles or videos. Because, learning in real-like scenario might be more effective compared what we could learn from books and videos.
Long term swing trading could be possible everyone but day trading must be profitable only for the pro traders. Swing trading usually demands derivative accounts but for BTC/USD pair we can swing trade even in spot markets which may help to eliminate liquidation pressures.
