Timeframe - 1 day. This chart clearly shows what the 30,000 level zone is and why it is so important, and for the second month there is its retention in the local channel. This zone acts as a "neck" level of the figure of technical analysis "head and shoulders". If this zone will be broken through and the formation will work out its price target, thereby the descending wedge in a small trend (3 months) will be completely formed.
I would like to point out that during the market dump at the end of 2018, everyone similarly waited for the price to drop to the highs of 2013, just like now to the highs of 2017, in the end they didn't wait. But there is a possibility that short term the price could reach those values. No one knows exactly how it will be, even those who "plan" and influence the price, because the world is global and everything is interconnected. Any event of "people driven by fear and uncertainty about the future" pulls everything along in a domino effect. In trading, there are only probabilities, more or less probable. But there is no doubt that BTC as a "recognizable brand of the process" and following it the entire cryptocurrency market will evolve. At the peak before the sunset, even a homeless person should know about BTC and XRP. This is not that period.
Also pay attention to the change in trading volume over the past 3 months.
In what zone is it more rational to buy BTC if you are not a trader? This applies to real and imaginary "investors" (gore-traders). It may be more rational to buy (plan) in both zones, but mostly in the more likely price reversal zone, as you think. At least learn to think and make decisions on your own, without outside influence.
If, say, you buy now with some of the allotted money. The price has not fallen below. From that zone, the rise has begun. You will have an asset + unallocated money.
If you bought with part of your allotment now, but then the price collapsed, you have money left over to buy in the next reversal zone.
Your average purchase price will be between these two zones, but it also depends on how much volume you bought in zones 1 and 2. If the volume is 50/50, it will be the average between the two zones. Let me remind you that this is for those who are not traders at all.
Traders, in my opinion, should not be doing this, as much as they can rationalize money and market situations. Make money on volatility.
