The market leadersBitcoin and Ethereumrejecting lower prices has created a sense of sustainability in the crypto market. As a result, a handful of altcoins jumped higher today, trying to regain lost ground.

After a significant crash in the cryptocurrency market due to the FTX bankruptcy, Ethereum’s price has dropped to a decisive support level of $1K.

A further decline is expected if the mentioned level fails to hold. The upcoming price action should determine Ethereum’s mid-term direction.

During the intraday trading session on 21 November, there was a significant surge in the whale holdings of ETH.

A mixture of high-profile bankruptcy fears, regulatory pressure, and rampant short selling have crushed the price of Bitcoin.

Every time a major centralized exchange blows up, a common question that comes up is whether or not we can use cryptographic techniques to solve the problem. Rather than relying solely on "fiat" methods like government licenses, auditors and examining the corporate governance and the backgrounds of the individuals running the exchange, exchanges could create cryptographic proofs that show that the funds they hold on-chain are enough to cover their liabilities to their users.

Even more ambitiously, an exchange could build a system where it can't withdraw a depositor's funds at all without their consent. Potentially, we could explore the entire spectrum between the "don't be evil" aspiring-good-guy CEX and the "can't be evil", but for-now inefficient and privacy-leaking, on-chain DEX.

This post will get into the history of attempts to move exchanges one or two steps closer to trustlessness, the limitations of these techniques, and some newer and more powerful ideas that rely on ZK-SNARKs and other advanced technologies.

Binance’s Changpeng Zhao and Coinbase CEO Brian Armstrong support Vitalik Buterin’s idea for how exchanges can maintain transparency for their customers. Buterin suggested a system where users can verify their personal balances through a Merkle Tree, protected with the privacy of a zk-SNARK (zero-knowledge succinct non-interactive argument of knowledge).

Shiba Inu & Dogecoin investors are least stressed, study finds. The study shows that FTT token (FTX) holders are the highest stressed-out group at 37.99%.

In a sign of momentum for Layer 2s, Matter Labs, the team behind the nascent zkSync 2.0 network, raised $200M in a Series C round led by Blockchain Capital and Dragonfly, the venture announced on Nov. 16.

Ethereum whale and shark addresses are reportedly “rapidly” accumulating the second-largest cryptocurrency by market capitalization at a time in which cryptocurrency prices have taken a bearish turn.

Bitcoin price returns to $16K amid warning over BTC whale selling. Bitcoin's modest recovery from two-year lows comes as major BTC price support emerges at $12,000.
