Bitcoin Roller Coaster Ticker - Update - Live prices for several Cryptos

This is the Bitcoin Roller Coaster
- Changed to live stream prices.
- Added button to cycle through 4 cryptos.
-- Bitcoin, Ethereum, Litecoin, Monero
The coasters used to get the prices from Coinbase or Coindesk about every five minutes. This update was because someone wanted a Monero coaster. In order to display Monero, I needed to change to the price source. I changed to Binance using websockets (like I use on the Nixie and Pinball head tickers).
I updated the code to live stream prices and to be able to select 1 of the 4 via an added momentary button placed on the back. The graph (bars) reset each time the Crypto is changed and are now 2 minute bars although the crypto is a live stream of the price.
(If you have one of the originals and would like it updated, you would need to send it to us, pay shipping both ways, and $10.)
