BTC - Finding the Bottom

So i have made out my chart, ive kept it simple and done simple time analysis as well
im expecting that by the end of the year (somewhere between october and mid jan) we should see btc somewhere around 8.2k
Personally, u should start ladder buying from 12k onwards
The green box represents the buying zone for btc

P.S. This will take time to play out since this is on the weekly timeframe
