They've said their thoughts based on their analysis. For me, I think that the $100k in this year is possible. Maybe it won't be exactly $100k but Bitcoin could attain a price as high as that. Also, do not really follow what these people say; do not make investments based on others' thoughts. DYOR and make your own guess (it's all guess work anyway).
That's right you don't wanna take those analyses spreading around the internet yeah maybe some of them do hit it right but it doesn't mean they will always get it right. It does not how it works, you should know that this market was still unpredictable. The best way is to make your own research because you know what would be best for you. Anyway, IMO, since Bitcoin is having kinda correction right now you might get the opportunity right now since I don't think whales and institutions are done accumulating, Bitcoin could grow even more, might be $50k before the end of the month who knows just be ready.
