The price of BTC and others altcoin declined because of bad news from China goverment and Elon Musk at the same time. In crypto, there are always 2 trend, bearish and bullish and for each trend can be taken for 2-3 years, and the trend changing for every 3-4 years. But for BTC, the price is always going to new ATH for every bullish season. This is according to history of BTC price. I think for now, the market will continue with bull season until 2022 and then the market changing to bearish season again for another 3 or 4 years.
