The real question like in any other regulation is if the Uzbekistan government giving people any kind of guarantee that their funds are safe in the hands of these centralized companies in return for all the monitoring and taxes they pay.
This is a very intelligent question. If the government wants to control or to a large extent oversee the activities of these exchange firms, then they should also take higher responsibilities. Just as Central Banks regulates commercial banks and assist clients in the recovery of deposits when such banks goes bankrupt, the government should also insure deposited funds in these crypto exchange firms.
The government should not just enjoy the huge tax generated by these firms and fail to protect their citizens. Sometimes most of these exchanges are connected to some powerful government officials that benefits from the raise and ultimate fall of these exchange companies.
Uzbekistanis should ensure they use these platforms for daily transactions but bitcoin investment or huge funds should always remain in non-custodial wallets.
