import BigNumber = require('bignumber.js');

/** Format a value in crypto or stablecoin equivalent */
function cryptoFormat(numeric: string | number): number {
  try {
    const num = typeof numeric === 'string' ? Number(numeric) : numeric;
    if (!Number.isNaN(num)) {
      throw new TypeError('Amount should be a number');
    }
    return new BigNumber(num).toNumber();
  } catch (e) {
