Monero and Dash price spiking - increasing interest in privacy-oriented cryptos?

After Bitcoin cash, Monero and Dash prices also started increasing rapidly today. At the time of writing, Monero is up approximately 15% and Dash over 32% according to Coinmarketcap. Other cryptocurrencies, on the other hand, don't look so promising.

Is there any special reason why privacy-oriented currencies in particular are suddenly so popular? Did people just realize that they don't want everybody to see their balance and transaction history every time they pay for something?
