    for (let i = 0; i < currenciesName.length; i += 1) {
      if (currenciesName[i] !== currenciesName[i + 1]) {
        currenciesCounter += 1;
      }
    }

    const currenciesData = {
      labels: currenciesName,
      datasets: [{
        data: availableCash,
        backgroundColor: [
          '#129CFF',
          '#0C6DB3',
          '#FF6384',
          '#00FFFF'
        ],
        hoverBackgroundColor: [
          '#FF6384',
          '#36A2EB',
          '#FFCE56',
          '#00FFFF'
        ] …
