Trusting myself to make every decision in investing is very good I think, because indeed every prediction by several experts has a different view and so does the realization, it is very uncertain.
Regarding the price of Bitcoin which will reach 120k in the next year, there is nothing wrong with that prediction, because it is very optimistic that it can predict that, but again we all have different views.
Personally I am optimistic that the price of Bitcoin will rise but not significantly so that it can reach 120k in a short time.
When experts write bitcoin predictions it will be a different view, because some people see him as an influential person so there is a reason why many people follow him including in the crypto news media.
There is nothing wrong anyone can write the price of bitcoin according to their beliefs where bitcoin will go next year after Halving, when you already have a bitcoin price target it means there is already bitcoin in your wallet.
It will definitely go up, I still don't know when this upward recovery will occur, I think now we have to wait for the Halving first.
