When it comes to trading the financial markets i dont agree with the saying "2 heads is better than 1"
You can actually gain from a friend or from someone that have experience, but you yourself is not complete if you do not know the A to Z of trading.
That's is because in the crypto markets a thousand people can perform analysis together and collectively decide to pump or dump a coin and the trade will still go against them..
That is called manipulation. There are many people that have gained through pump and dump, but they are scammers.
This happens a lot, time and time again, that is why its better to always seek first the knowledge of trading, that will take you much further than collectively deciding to pump or dump a coin as newbies
You are right, traders needs to know about how to trade, and also have the full experience. But, not new traders are pumping and dumping coins, it is part of scam means of having the larger gain while investors (especially the late investors) will lose.
That is why we should go for cryptocurrencies like bitcoin that is not subjected to pumping and dumping.
