The channel drawn on the Bitcoin chart is not an Elliott Wave channel, its just an arbitrary classical Technical Analysis trendline capturing the most points on a trend; of which, a number of interpretations can be made.
I say again that I am not talking about the channel,
I'm talking about line 2-4
And I don't think it's normal for wave 5 PRIMARY to break line extension 2-4

Don't see it as an issue, happens all the time. If this didn't happen, the charts would be picture perfect and very predictable !
