For me it's sounds like FUD to me dude i think it is very hard for Bitcoin to reach 100,000 usd
It is just a prediction that the Bitcoin price can reach $100k. But I don't think it is FUD, bro. Some people who predicted it are experts and experienced investors/traders. They have strong reasons to state the price of Bitcoin can reach $100k or above. They learn it from analyzing the chart patterns and they also consider it from some fundamental aspects.
That's not FUD actually its FOMO that encourage more people to buy before its too late.
This is just indeed a prediction only and its up to us if we are going to buy or not but if we are talking about Bitcoin here, I have more confidence to hold this than to any altcoins because I know, Bitcoin will also grow and we are still not in the mass adoption so imagine the future price if many people started to use Bitcoin.
