I did a test transfer of 1 XRB form Kucoin to Binance and it successfully transfered but it took 16 hours to final arrive at Binance, I'm now worried that if I try to transfer the rest of mu XRB it will never get there.. It might be OK this time as I'm transfering more the 5 XRB and Kucoin say this requires a manual process, so hopefully a real person will be checking that the transfer has worked.
