They have chosen Binance Smart Chain. Imho it's a better choice creating better listing opportunities. But what it comes to CMC or coingecko, it's a brand new exchange, so it's not listed in anywhere yet. Apparently betfury devs saw this with most potential and they have already looked at the code, so i guess we are in good hands.
I'm also voting for Binance smart chain have added Biswap to many wallets too, I checked it on both Coinmarketcap and Coingecko and it's not yet listed since they are new I expect both token Biswap and Betfury token, to get listed on both Coingecko and Coinmarketcap the volume is already great on Biswap, these two projects are ready to explode in the coming months.
