According to Twitter user yieldchad, Celsius may be technically insolvent.
The project has a total of 1 million ETH, but only 268,000 (nearly 27%) have sufficient liquidity. The other 445,000 is Lido’s stETH, which can only be exchanged for 287,000 ETH at the current Curve exchange rate.
The last 288,000 coins were directly pledged into the Ethereum ETH -0.80% 2.0 contract, and they would not be available for a while (at least one year). At a rate of 50,000 ETH per week, Celsius will run out of liquid ETH in five weeks.
