Who knows? The situation is deep. It is really hard to restrict to buy crypto. Investors from China will anyway have easy-to-mid level difficulty to buy cryptocurrencies. But the question is - will they invest at least half of the amount possible in no restrictions situation? Probably not. But even loosing Chinese investors at all will not make the market too bad. Maybe minus 15% market cap in long run. This is in worst case scenario. But the industry is growing so fast, that those 15% will be recovered very soon anyway. Crypto industry is strong now!
