Crypto exchange Coinbase has suspended retail staking services in California, New Jersey, South Carolina and Wisconsin. Cryptocurrencies staked prior to the order will not be affected. The U.S. Securities and Exchange Commission (SEC) filed a lawsuit against Coinbase last month for classifying its staking service, as well as several of the tokens it lists, as securities. On the same day, securities agencies in 10 states began filing lawsuits against Coinbase. Coinbase said in a blog post on Friday afternoon: "Strongly rejects any allegation that our staking services are considered securities. However, we will fully comply with the state's preliminary order if necessary, even if we have not yet had the opportunity to defend ourselves."
