Binance did not give a reason, but I think the problem comes from trading habits in local exchanges instead of an exchange from China, and this leads to trading volume and liquidity of the exchange are lower than expected. This seems quite different from many other territories, even in Vietnam, we consider Binance to be the best, largest and most engaged exchange in the world. Hope Binance will have other more effective strategies to attract the attention of European users, because they are still the largest exchange in the world at the moment, even owning a very strong blockchain.
