What do you mean under the crash?
Just open the coinmarketcap or another list of coins with charts and changes of prices and you will see that most alts are rising. This grow is almost since the beginning of December.
For example XRP and XLM made x4-5 (and even more) since the beginning of Dec. LEND also grew rapidly. And there a lot of other altocoins with good results.
Now prices went down for a bit but this is not a crash this is called correction.
Soon the prices will go up again
