Graviex

Graviex is a Russia-based cryptocurrency exchange which optimizes for high resolution orders, low order/withdrawal fees and a no-frills experience.

At Graviex you can trade GIO tokens. GIO tokens entitle holders of GIO daily dividend payouts of BTC directly to you exhange account proportional to the trade volume on the exchange.

I've used the exhange before and it's quite good. Holding the GIO token in the exchange pays out BTC daily as advertised. Their Telegram chat support is very rapid and support tickets are answered with a day in my experience.
