There are a lot of reasons as to why the crypto market drops. First you have to remember that the whole market is volatile because much of the market is speculation. Not all projects but I would say most of them are based off speculation or scam. Remember that there are at least over 1,200 crypto coins and possibly many more to come. Another reason why the market can keep dropping is because of the fud that gets thrown around. It's obvious that whenever a mainstream source in the news talks about btc, they don't every really do their research or refuse to and talk trash about how it's not real money. lol And that brings up the last thing that can really cause downtrends is btc itself. The cryptomarket usually follows what btc does, but this will all change in the coming years as more and more projects come out with more utility and better word of mouth for btc as it's realized as a store of value and payment system rather than just a use for daily currency.
