I've posted several Gann-Square-based analyses for the BTC market, but I feel this one could be the best of those.
If BTC marks a new low at least on the daily timeframe, which I feel is likely, my Gann Square should underline 24.25k and 19k as primary, and Gann Fan does 23.4k and 22.1 as secondary.
But, most importantly, Gann Square and Arcs spot support and resistance on the time axis. If it is correctly working, and it looks like it is, we will soon reach the vacuum zone on the time axis, where we must witness a significant price action.
That would be roughly around June 12, obviously imminent. But this may not be particularly surprising if we simply look at the candlesticks.
