Typeerror: Cannot read Property 'Brl' of Undefined [Discordjs]

Question

I’m trying to do a function for my Discord bot that does a request on a cryptocurrency api, it’s working normally if I put the cryptocurrency name manually in the api, but I would like to use an args.Join to make the request be done through the Discord itself, but it gives the following error: Typeerror: Cannot read Property 'Brl' of Undefined.

const Discord = require('discord.js')
const axios = require('axios')
const client = new Discord.Client()


module.exports = class extends Command {
    constructor(...args){
        super(...args, {
            aliases: ['eth']

        })
        
    }

    async run(message, args) {

        let cripto = args.join(" ").toLowerCase();
        let getCotacaoBTC = async () => {
            let response = await axios.get(`https://api.coingecko.com/api/v3/simple/price?ids=${cripto}&vs_currencies=brl,usd&include_24hr_change=true`)
        
        Cotacao = response.data;
        return console.log(Cotacao)
    }   

        console.log("Criptomoeda: " + cripto)
        let Cotacao;
        let cotacaoBTC = await getCotacaoBTC();
        let brl = Cotacao.cripto.brl;
        let usd = Cotacao.cripto.usd;
        let variation = Cotacao.ethereum.brl_24h_change;
        let formatado = brl.toLocaleString('pt-br', {style: 'currency', currency: 'BRL'})
        let formatadoUSD = usd.toLocaleString('en-us', { style: 'currency', currency: 'USD'})
        function criptoF() {


        if(variation > 0) {
            let embed1 = new Discord.MessageEmbed()
                .setTitle(`${cripto}`.toUpperCase())
                .setColor("GRAY")
                .addFields(
                    { name: `Cotação Atual BRL`, value: `:flag_br: ${formatadoUSD}`, inline: true},
                    { name: `Cotação Atual USD`, value: `:flag_us: ${formatadoUSD}`},
                    { name: `Variação`, value: `:chart_with_upwards_trend: +${variation.toFixed(2)}%`}
                )
                .setThumbnail(`https://upload.wikimedia.org/wikipedia/commons/thumb/0/05/Ethereum_logo_2014.svg/628px-Ethereum_logo_2014.svg.png`)
            message.channel.send(embed1)
        }else if(variation < 0){
            let embed = new Discord.MessageEmbed()
                .setTitle(`${cripto}`.toUpperCase())
                .setColor("GRAY")
                .addFields(
                    { name: `Cotação Atual BRL`, value: `:flag_br: ${formatado}`, inline: true},
                    { name: `Cotação Atual USD`, value: `:flag_us: ${formatadoUSD}`},
                    { name: `Variação`, value: `:chart_with_downwards_trend: ${variation.toFixed(2)}%`}
                )
                .setThumbnail(`https://upload.wikimedia.org/wikipedia/commons/thumb/0/05/Ethereum_logo_2014.svg/628px-Ethereum_logo_2014.svg.png`)
                channel1.send(embed)
            }
        }
        criptoF()
        

    }
