This is for beginners traders because I now old traders like know these already.
You set indicators, the market fall to where you supposed to buy, like in an oversold market, you buy the coin, thinking the price will start rising. The market show as if the price will start rising but the later continue to fall and fall the more. In the process, your money got liquidated. Your tried it for overbought market but the same thing happened and your money got liquidated.
Old traders, if you need to give advise, what are they?
I can't agree more, the advice you gave covers the most painful lessons most traders learn through actual losses, so any beginner reading, take it seriously, and keep them in mind when trading. Actually write them down.
Newbies should understand the difference between trade and investment too that they can do by understanding the different types of trading first. They also have to understand what is diversification and averaging, because both are tools for risk management to increase profits.
Finally protecting our capital is above everything else, an account down 50% needs a 100% gain just to break even. So it does not mean we should stay small, when market is 50% down, don't wait for break even, buy more if the coin is bitcoin, because by the next break even price you will recover your capital plus the 2x profit.
