It's August 9th, 2022. It's been two months since I put an order to buy 9 HBD for BUSD on Ionomy.com for 0.99 BUSD each. I'm also selling 4 HBD for 1.008 BUSD each. So far, I was only able to sell 3 HBD in two months! It takes a long time for the market to take offers with this pair.
You'll pay a trading fee. You pay a withdrawal fee for either trade. Check the fees before trading depositing and use limit orders. A liquidity pool would make things more economical for those who want to trade between them. I'd like to see it happen.
But the way I see it, few HBD have owners that want BUSD and vice versa. If you are one such owner, for now you can get it at: https://ionomy.com
