Industry Briefing

According to CoinMarketCap, the total cryptocurrency market cap is down to $1000 billion, the new lowest since February 2021. Especially, this week, stEth has aroused huge panic that ETH price sharply goes down. This is also related to the nondisclosure of real loss by Celsius Network. And for DeFi and NFT, we can also see the downside for both. The Federal Reserve believed the crypto market structure is vulnerable regarding the slump in stablecoins and the recent crypto market situation in its Monetary Policy Report.

Then, choose the right solution to have the security really works for you.
