Transfer from Binance to Orionx (exchange)

Hi everyone,

I transferred BNB yesterday from Binance to Orionx exchange (to a friend), I've done it before, the address and memo are correct and the transfer was successful. Though my friend still didn't receive it. It's been around 17 hours and I'm getting a bit nervous about it. We're thinking that the transfers don't work during the weekend, but I'm not sure if that's correct.

Thanks!
