v0.3

Version 0.3 supports 12 coins (bitcoin, ethereum, litecoin, waves, binance coin, monero, stellar, cake, bsw, eos, dogecoin, zcash), can be increased to 100 or even more. A request to the coinmarketcap API occurs every 5 minutes. Coins change every 25 seconds (5 minutes / number of coins).

Now there is a separate server between the coinmarketcap and the wifi module, which simply removes unnecessary data from the coinmarketcap response. This is necessary because the wifi module can process a JSON object of no more than 4096 kilobytes.

v0.2

Support few cryptocurrencies (Bitcoin, Ethereum, Litecoin by default)
