Yes, to be honest people who think that bitcoin will continue to go up in a straight line are people who want to quickly take advantage of this. sometimes, they end up saying that bitcoin is a scam.
they should have done their research by looking at market prices from year to year to get a big picture of what bitcoin is like. however, sometimes people who think like that only see the price changes that are currently happening. they are assuming, if they had bought bitcoin long ago, they would have made a huge profit today. and they invest in ATH, the price corrects again, and they panic, sell their assets, and brand bitcoin as a scam.
