Well, BTC is performing well if we look at its yearly and monthly charts. We can easily spot the changes. But I don't know why you are panicking about this downtrend. BTC is a highly volatile asset, and its prices change with time, so it's not a big deal. Yesterday, BTC's price dropped, but in the next movement, BTC went up again, so don't panic, Bitcoin is behaving normally.
Now, coming to another point, halving was never mentioned to suddenly raise the price of Bitcoin and start a bullish era. We need to wait, give it some time, and also take advantage of it. When Bitcoin goes down, take some part and wait for the next downtrend, which we normally call DCA methods.
