BTC and ETH are long and short. Is it a major trend change, or a short-term deep correction?

Yesterday, a friend left me a message saying that the general trend of BTC and ETH is still bullish. Why have they fallen so hard in the past few days? Is the general trend changed, or is it a short-term deep correction? But this is also true. The trend in the past few days is indeed obvious. The short-term cycle needs a deep correction, but where is the lower support? Will it go down directly, and it will be difficult to go up to the 12,000 mark and above 400?
