I would answer that question by reiterating the importance of taking action to regulate the technology so that people know what they mustn't do, and in particular, to establish institutions to regulate those who take initiatives and seize opportunities in this field.
For example, one of the reasons why I was willing to visit a cryptocurrency exchange platform was that it had a registration number from the Financial Transactions and Reports Analysis Centre of Canada. It's reassuring for consumers to see that these platforms are regulated. That doesn't mean that they won't still be able to play games with money, given that human behaviour is not infallible. Our authorities, institutions and governments nevertheless need to establish systems to approve startup companies, perhaps even by encouraging the various financial market authorities to create sandboxes, and ensure that these businesses are properly guided and structured from the outset. That would be very reassuring to citizens.
