Probably it's between last week of April to 1st week of May.

If we can based on past history, yes, usually bitcoin halving is the final catalyst for a bitcoin bull run. How big it is? we really don't know. Conservative estimates put it at around $100k at least, so you do that match.

Last all time high is more than $60k and there are also numbers being thrown that the next ATH will be 2x or 2.5x of the previous run in 2021.
