Why does the whole criptomarket fall?

go mass correction.
Maybe you should move this to the enomics section or the speculation section. This isn't the proper place to ask this.
Regarding your question, it is indeed a market correction. But I think it's temporary. Sometimes there is a whale that cashes out a big chunk of btc and that brings down the price and then panic ensues. Now the whale has the chance to buy cheap coins.
