In fact, the current trend surprises us. But we will be cautious when investing this time, dumps is a thing that we don't have to forget, correction is huge possible to happen next.
Exactly, I'm having the same thought too, yesterday the market ended in a negative way as bitcoin lost some value which also saw many altcoins dumping massively. Although the price seems to be recovering now but lets not be too quick to judge as there's every possibility another dump is on the way that will most likely take the prices of bitcoin back to the price range of $21k before the next bull leg beginning to form.
No expert will give you an accurate result even though how good they are on chart reading since the result still may depends on what will happen in future. If there's no bad news floats next year then maybe we could reach that but since the $30k is just quite near to the current price then the possibilities is huge.
What most so called experts are doing right now are just speculating without having any backing since they are only relying on the hopes of bitcoin continuing this upward movement until 2021. While the new milestone of $25-$30k is quite possibly for bitcoin we have to see how the market react to the correction that's due to occur. Although the market is showing signals for this development but it seems the market isn't ready for that yet and it'll cause many traders to panic and sell their coins which will push the price more downward.
