I don't know man, I would assume many people that have Binance accounts also have Kucoin accounts.  The UI/UX experience (while better at Binance) is very similar across both sites.  I'll say virtually everyone I know that trades cryptos has an account on both sites.

They should've never opened registrations back up at Binance, the BCD/BTC trading pair page is a freakin blackhole *sighs*
