Yes the the one person is me whosold at what I thought would be the peak ($5k) hoping to buy back in at a dip around $2k again.. it never happened. They're all speculators, the people saying a "dip is imminent". It might be, it might not be. If they're right, they'll boast about it, if they're wrong, you won't hear them mention it again and it will be forgotten.
Which is why it is useless to try to predict what the market is going to do, the market is going to move independently of what we want and yet people make all kind of predictions about what the price is going to do and even worse they put huge amounts of money behind their words and when their predictions fail instead of blaming the methodology that they use to get those predictions they blame the market as if the market did something wrong.
Who estimates price based on any analysis type, but there are so many ways to predict. Maybe they try the right way. The fact, cryptocurrency is often unpredictable and sometimes it makes the analysis usless. Maybe chance also helps.
