Reducing Funds withheld by Grid orders

I prefer 3C Gridbots over those that Exchanges offer. However, the Exchanges do not place a hold on funds used for all the orders in a gridbot. When I set up a grid bot on 3C, some of my funds are reserved for the orders associated with every gridline in the bot. This eats up my available funds pretty quickly so that I can use 25-50% less of my funds toward other bots. I don’t have this issue when I set up Gridbots on Exchanges. They only reserve the amount invested when I set up a gridbot. There’s no deduction of funds for subsequent orders in a grid bot. It would be a great value — and make 3C more competitive if 3C can find a way around reserving funds for the orders associated with every grid in a gridbot. Cheers!
