$Tiger Brokers(TIGR)$$Futu Holdings Limited(FUTU)$Futu and TIGR already came out with release that they will fully comply with all laws, so I do not think the apps will be banned. Normally Chinese hit the first company the hardest to ‘kill one, warn the rest’ so with the statements, it will be back to normalcysoon. Even if there is a fine, Alibaba was fine 4% of revenue while Meituan was fined 3% of revenue for anti-trust, the amount of fine will not be anywhere at that level. 

As for being listed in US, there are many Chinese finance, insurance companies, listed in US, to stop Futu and Tigr would mean stopping all US listings, which Chinese regulators already said is not the aim. 

On the impact on society, allowing Chinese people to invest in overseas equity to grow wealth is a lot healthier than to allow them to buy 2nd or 3rd properties to grow their wealth. When their wealth increase, their disposable income and consumption will increase,leading to common prosperity. 

So I think the Chinese regulators will realise  online brokers with educational and analytical tools charging Low rates is a way to help the middle class grow their wealth and a necessary means to achieve common prosperitywhile relying less on pensions if savings canmultiply a few folds before retirement, the developed high income countries have long done this to grow wealth, even the Chinese state owned investment companies invest overseas to grow wealth. 

China often models after Singapore. Chinese wants its citizens to be self reliant for retirement given the ageing population and so I think it will support Futu and TIGR in the longterm. Both of them have licenses in Singapore and pass the strict regulatory requirements, so I think they will be ok.
