Monero jumped up by 50% today. Not uncommon in the cryptocurrency space.
I've been using various exchanges to trade cryptos but really like Bitfinex.com most.
There are several coins at wildly different values:
Bitcoin at $4000/coin -> Ripple at $0.07/coin
You can spread your investments across several coins and if you like to day trade the interface pretty nice.
It took me a little while to realize I could pinch and zoom the graphs with my trackpad but other than that the interface is pretty intuitive.
Are you guys trading cryptos? What are your favorites?
