About a week ago I found very useful website constructor of cryptocurrency widgets. You could use it to show-off crypto rates at any event (on the vertical screen or projector (for example)). So I decided to tell steemit community about this!
LINK - SYMBOL1,SYMBOL2,...&tsym=CURRENCY&eventLogo=IMAGEURL
As you can see, you can choose cryptocurrencies AND fiat alternative (let's say, dollars, roubles, euros, etc.). Just specify the cryptocurrencies names in URL and the target symbol (tsym) and update the page. Viola!
or https://www.cryptocompare.com/full-screen/conference?fsyms=ETH,BTC,STEEM,SBD*,GOLOS&tsym=USD&eventLogo=https://image.url
Last thing is to open your web-browser in fullscreen mode on vertical screen. It's great for any crypto-event!
Okay, now you know how to build a cryptowidget page and display it on your event. All data is taken from cryptocompare live stream, so the rates will update in live.
Have a nice event out there,
