I'm sorry, I'm not that articulate in expressing myself. What I mean about the big exchanges, I'm reffering to Binance, Bybit, Huobi, and etc they have been dominant for years and when faced with challenges they begin withdrewing from that country.
If the demand for regulation contradicts the general purpose of the service, while there are no alternative solutions then it is better to withdraw from that country. Or in other words, the new policy may not benefit the exchange in the long run (substantially reduces a significant portion of exchange income).
