It is easier for Chinese to be gubbed. A few years ago (about 2015~2017), many Chinese used locust surebet strategy to make large profit, i.e. open multiple sets of accounts with their friends and relatives’ ID. Also, I saw lots of hiring notices online, which hire apprentice, train them to surebet and collect a certain part of their profit. There were so many Chinese doing the same thing. As a result, when a Chinese opens account, the bookie will potentially mark this guy as a sharp player and limit comes quick.
They also rent VPSs (usually with Hong Kong IPs) of course. If you use a HK IP, you will be limited even quicker. Don’t ask me how I this! I got limited after one bet.
