A custom coded always-on crypto price display

I created a script that displays the real-time price of any coin. The purpose of this is pretty simple – I can always see the price of Bitcoin, Eth, Ton, and others. (Works with pretty much any coin since it pulls in real-time prices from OKX).

It’s been pretty handy for me so far, but now I’m thinking of upgrading it a bit.

Maybe you have some feedback or better ideas? My ideas right now are:

1. I could upgrade the script so it can track the balance of the user's wallet. This could be easier to understand than the price of a coin.

2. I think it’d be awesome if the script could also display NFTs held in a wallet.

3. Displaying the price chart of a coin.

I know it's basic stuff – this was just a random weekend project. But what do you think of this idea?

Also what’s your take on OKX? Is it good enough for price tracking and calculations? I like that their API is free, unlike Coinbase, CoinGecko, and CoinMarketCap, which need a subscription.
