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).
indeed we do not always have to trust the analysts they inform because it could be misleading. but our analysis can also be used as a reference from past experiences.
If in my opinion, seeing from the first and second halving that bitcoin has made, that their% difference can be 17x, then the possibility of $ 100K will easily be done by bitcoin this year.
for me, the most important thing is the improvement of all the top altcoin rankings, let there be a renewable ATH because this will provide a sharp increase for new atcoins that want to grow from projects that are being marketed, let the bounty heyday of 2017 can happen again this year too.
That is the point of analyzing something, you can end up with wrong ideas, but you could at least see what is it saying and you could either use that if you want to and hope that it is right or you could just use that as guideline and that's it.
I personally believe that bitcoin may not be doing that bad in the near future, I mean this week, but the charts do not say that as we all have seen, now did I used charts to decide? No because charts said it should go down but I said it will go up, so where did I used the charts? You could look at charts, and why it says it will go down, and you could look at the past, and see similar charts that said it should go down but the real price went up instead, and use that as an indicator that whenever the charts show it will go down because of X reason the price goes up, and figure out it will go up again this period.
