There are several things that crushed market upto 8000$ just in 18 hours and market has protected it's 95k support but if the selling pressure will continue then it can drag the market towards more crash.
Behind these crash the most important news was that yesterday America said that we don't want to cut interest rate in January which has become the big reason of crash.
The second reason was that many trader has opened a long position with high leverages which has increased the greed rate in the market due to this reason market has taken down side suddenly which is called a normal factor of the market.
In this situation the most profitable coin will be xrp, pol, ICP and dot which can provide us good profit in the upcoming Bull Run, on thing we should keep in mind that after this crash if btc got stability above 100k then we can expect a huge rally and the rejection might not see again upto the next 45 days
