I know for Bitfinex, and I am very happy and positive on that, only wondering if there is another B around the corner like Binance, cause CLO made the audit for BNB, and also CLO is available on Trust wallet, the official Binance wallet
For me, this is maybe a start for the listing there
And yes, I am a big supporter of CLO, thats right

If there are other Bs, the team would have stated Bs, not B.
So, I think you have over-waited for another B, or other Bs.
For CLO wallet, at the first time, I did not know how to get my CLO from web wallet, because I was familiar with Myetherwallet, not CLO wallet.
Anyway, with help from community, I solved it months ago. It's the way CLO community shown its power, helpfulness.
