Which is the $BTC/USD trend?

The cryptocurrency market plunged last week, but recently it has stopped declining and is rebounding.

BTC is currently around $18,000, but I liked it because I completed a beautiful double bottom in 4 hours.
It has turned to a rise. It is likely to rise to the resistance level of $ 18,500.

Most recently, this $ 18,500 is expected to be the key.
If it breaks well, it's definitely going to be the highest ever, $ 20,000.
Momentum and attention will also increase.
If this happens, we will see a breakthrough of $ 20,000 by the end of the year.

On the other hand, if the price cannot break below $ 18,500, the downtrend will continue within the year.
If that happens, we have to consider a drop of up to $ 16,000.

ETH 2.0 upgrades are coming up this week, I want to be prepared for sudden development.
