Updated to use @r3s-ash fork: https://gist.github.com/r3s-ash/fe6d7a93e4f540c670ccb81ddf34516d

Update line 8 to:
id=$(curl -s "https://api.coingecko.com/api/v3/coins/list" -H "accept: application/json" | jq --arg arg1 "$1" '.[] | select(.symbol==$arg1)' | jq .id)

To correctly take position argument and make last API call based on value of ID instead of symbol
