If we will take a look at the chart and on the 2nd halving part. After the 2nd block halving there you see a new all-time-high.
So, for me, probably like months after the block halving we can able to see a new all-time-high, like probably as what others said: The year 2021 is when the Bitcoin is probably getting its new all-time-high.
I just got back into crypto and saw about these few weeks ago. Still looking forward to what it will gonna happen. It was the first time I will witness the halving of bitcoin. But based on some sources I've read we might really see a good result this 2021 which is already predicted few months ago.
Those predictions are based on the history of the past 2 halving which resulted into a bullrun few months after the halving. But, this doesn't mean witnessing a good price on 2021 is guaranteed. Remember, the Bitcoin block halving ain't about the price growth, but it's all about the literally halving of the miners' reward.
However, a lot of people were fond and optimistic about the halving, thus It's giving a boost on the price movements because it will encourage the mass investors to pour more money in cryptocurrency.
