btc long term trend line excluding parabloic rallies .

this long term trendline shows btc price action excluding paraboic runs .
now you can see that when we are above this trend line and it acts as a support we are in start of a parabolic run .
so if this be true and the price stays above almost 12800 and this trend line acts as support we can be in start of a parabolic rally and see ATH in 2021 .
this is just my theory and it can be wrong .
