MXC is a good exchange according to the traders themselves. It's not a good entry-level trade because you can't deposit fiat currency, but it does seem to offer quite a large offer when it comes to altcoins and trading pairs. It has regular fees, and it seems to be very popular, the daily trading volume being quite close to that of Binance itself.
With advanced trading technology and security seemingly covered by two professional security companies, this trade certainly looks pretty safe and has good trading features, so this might be worth a look.
