Fixed the cryptotracker plugin

Switch to Binance API: To enhance the reliability and accuracy of cryptocurrency tracking, I have migrated the plugin to use the Binance API.

Use of USDT: With the transition to the Binance API, we are kind of forced to use USDT (Tether) as the base trading pair for tracking cryptocurrencies.

JSON Structure Update: As a result of switching to the Binance API, the JSON data structure received from the API has undergone some modifications. These changes have been incorporated into the code.
