Cannot compile

[therealsputnik]

Cannot compile. Some sort of json issue, but I don't know enough about json to fix it. Apparently this may have something to do with json 5 calls vs json 6 calls. (?)

The solution is to go back to ArduinoJson version 5.x.x which will allow you to compile; however, this library is obsolete anyway and you can no longer use coinmarketcap version 1. Code hasn't been updated for 2 years, Suggestion is to use another exchange that is still open without requiring an account... Like coingecko or Binance.
