Please consider adding more decimal places to the trading pair OPT/BTC.
At current limits of 6 decimal places, trading is stifled and HitBTC is losing out on potential trading fees that can be accrued.
With 7 to 8 decimal places such as with DOGE/BTC, more frequent trading can resume as ask/bid prices will be closer together.
The community wants to trade the token but not when there is a 33% swing between buy and sell price. This is an extremely simple fix which will lead to more revenue for HitBTC and an increase in trading activity on this specific trading pair.
