In Hong Kong, there was a big conference about Bitcoin, even though China doesn't allow commercial cryptocurrency trading. The conference, organized by BTC Inc, had about 5,500 people attending, with half of them from mainland China. The CEO of BTC Inc, David Bailey, said people were interested because Hong Kong is about to launch Bitcoin ETFs and might soon have Ethereum ETFs too. These ETFs allow people to use Bitcoin and Ethereum to buy shares, which they can then use as collateral for loans. Some companies in Hong Kong are working on making this process easier.
