Did something crash, huh? As I know all popular cryptocurrencies are growing in price in last few months. I also doubt that they will drop in price in the future. Only thing that can happen is crash of small altcoins (so called shitcoins) and it's a good thing.
yesterday I see one coin called augur bumped big in the market we may find the bump more in the chart. After that cardano, iota and all always growing in the marketplace.
Crash means you will find that coins like digicoin, qtum, utrust and some coins always fluctuate vin the market. So be choosy to invest on the altcoin.
