a lot of economists are very surprised by the development of bitcoin in such a very short time and unexpectedly by many people by making bitcoin a very popular business investment in this century so many people do not like bitcoin and slander bitcoin in any way they want. it can be mainly with paid buzzers to worsen the image of bitcoin among the people so that bitcoin falls at its lowest point and creates a bad opinion of bitcoin in the public eye, but this has absolutely no effect on bitcoin investment which makes it increasingly popular in the business world crypto
sometimes I think, people who vilify bitcoin also invest covertly, it's just their trick to get a low price, when the public starts to get excited and influenced, it slowly brings up good news so the price pumps again, and profit for them... well this is just my imagination 
whatever it is actually I don't really care, as long as this can give me the opportunity to earn money then I will use it well. Everything has a risk, if you don't want to take it, it will be difficult for us to grow. experience is the best teacher, if we lose then consider it a cost for learning, and after that we have to evaluate it so we don't get caught up in the same mistakes.
