It is always good to learn about price action before investing in cryptocurrency. Learning will guide your judgement in the market and prevent you from making decisions with instincts alone.
Yes mate you are right, no one can get profit without knowledge, but we can't predict market properly. As there are many reasons for market crush and China has announced something about Bitcoin so we can't predict it right.
It's true we can't predict the market properly but people are too greedy, they failed to follow the rules of crypto investment, everything that happens in crypto space today is all I was expecting because I am so disciplined to an extent that I believe in some shits like
1. Things don't stay up forever
2. Up and down is 100% certain in our lives and businesses
3. Billionaires that are hyping crypto wants more money themselves
4. People buying crypto when crypto is surging is RED FLAG
5. People looking at portfolio with 1000% gains and still refuse to take profits, that's their problem, 100% greediness
