Maybe Gann-arcs are not very relevant to bitcoin and/or the stage of bitcoin is in. This fact alone van can be deduced from the line representing "reasonable growth"; it tells us that we should be at 2600 ... in 2026.
Don't under estimate the power of Gann. That is a weekly chart, and what looked as though was going to be an exhaustion candle, actually closed as just another continuation candle. Target is now $3600:

If Bitcoin does break out above $2930, then in terms of Gann, it will be a repeat of 2013, but one scale up.

I find the Gann is a very powerful tool as a kind of market roadmap. Not very good for taking trade setups though. Other tools got to be used for that.
