The most important thing that every trader needs to know and understand is that what really matters in trading which is supposedly profitable is discipline, you have to decipline yourself physically and mentally because it is easier to lose money in the crypto world than it is to make profit and as a beginner or experienced trader it's not about the money it's about how well and vast your knowledge is about reading the chart, recognizing the higher timeframe trend depending on the type of trader that you are (scalper,day trader,swing trader and long term trader) and knowing which direction you are taking wether being it going with the trend or against it, calculating your position and size according to you capital ,knowing your take profit and stop loss and then knowing when to enter and exit the trade. Then trade demo account before putting in your money for real.
Without decipline and knowledge all these mentioned above wouldn't be possible but here comes the money part, without the money or capital to trade or invest, the knowledge isn't completely useless cause you can teach it but you need experience to understand the price action better,and you don't really know what trading feels like untill you open that position.
So with all these points what do u think really matters most money or strategy and knowledge???
