title: How to store cryptocurrency balance in mysql?
body: <p>Referred to <a href="https://stackoverflow.com/questions/46658847/crypto-currency-mysql-datatypes">this question</a>. In the marked answer said that the best way to store cryptocurrency in mysql is to store it as <code>DECIMAL(27,18)</code> or <code>DECIMAL(36,18)</code>. But <a href="https://stackoverflow.com/questions/46658847/crypto-currency-mysql-datatypes#comment93443119_48555882">comment</a> there makes me doubt. If ETH value has 32 bytes, then we can't store balance in this way. So what is the best way to store it? </p>
  
  <p>P.S. Except strings, I need to sort wallets by its balance value. </p>
