Volatility zone on BTCUSD

Here you can see 1D BTC chart,
Now we are in short term downtrend or retracement of uptrend which stated April this year.
On chart I add BB indicator and I marked using yellow circles mark low volatility in Price zones, but at these levels there are a lot trading volume which suggest another big move on BTC.
IF we break this downtrend channel it is possible to see uptrend swing but then we will see if it start 2020 bullrun.
Now we are probably at acummulation zone but there is still possible to price fall to 5,5k $ or maybe lower.
So keep it in your mind if you are buying BTC for longterm investing.
