The code has been updated to work with free Coingecko API. Besides that, a few UI tweeks on the display make it even more pleasant to watch.
All of the setup is similar to the previous version, so most of the instructions / video tutorials still apply. The main difference is that you now put your cryptos in the cryptos.h file. And the best for last... you can now add the logo to every displayed cryptocurrency! To do that you will need a bitmap of a 32x32 image that you put alongside coin id in cryptos.h file.

A display built with an ESP8266 that fetches live currency prices directly from the CoinMarketCap.com API.
I've tried to make this project as easy to make as possible. There is no soldering and you also do not need to know how to code. In total it should take 10-15 minutes. The total cost is also only about $8 or so.
Crypto Wallets (If you feel like tipping, obviously no need to!)

It should be wired as followed
| Pin On Display | Pin on NodeMCU |
|---|---|
| GND | G |
| VCC | 3V (some boards say 3.3V |
| SCL (Sometimes SCK) | D5 |
| SDA | D3 |
NOTE: Some displays have GND and VCC swapped around, always wire as above!
