I think it is quite safe to declare our first candidate, June 3rd, as the peaking day for SMA 200. BTC made a double top. First top coincides with this day (June 3rd), and the second top coincides with the 4th anniversary of SMA200 peaking day. If you play the chart, you will notice that price started declining when it entered the red zone.
It is still too soon to judge and close the case, BTC has some chance of making a higher highs (30% as of now).
PS: we should think about some tinfoil theories about these coincidences when things are settled a bit more.
