Generally speaking, exchanges between different cryptocurrencies are usually done by either a simultaneous swap of one cryptocurrency for another, or a deferred exchange, in which one cryptocurrency is sold for cash, followed by the purchase for cash, of a different cryptocurrency. It is worth noting that state securities regulators increased their scrutiny of digital assets during 2021. An area of particular focus has been exchanges and others offering interest-bearing crypto accounts. New Jersey and several other states issued cease and desist orders against BlockFi, a well-known crypto exchange, for offering such interest-bearing accounts. They range from blockchain projects to early-stage investors, exchange platforms, and other infrastructure providers. One thing that can definitely be said about blockchain is that it has brought together the financial services industry, and will continue to do so in the years to come.
EIOPA published a discussion paper and launched public consultation on Blockchain and smart contracts in insurance in 2021. The outcome of this discussion paper will help to better understand the developments and risks and benefits for the insurance industry.
