Just scrolled through this week's crypto digest and there's a lot going on. Bitcoin mining difficulty just took a massive hit, down over 11% in a single adjustment - the worst since China's ban back in 2021. Network's at 125.86T difficulty now, but projections show it bouncing back around 5.63% by late February.

On the altcoin side, things are pretty mixed. Some coins like MemeCore are running hot at 21% gains, but others like Monero and World Liberty Financial are bleeding out. Total market cap sitting around 2.37 trillion, with BTC hovering near 66.7K and ETH around 2.05K as of today.

Vitalik just liquidated about 2,961 ETH for roughly 6.6M a few days back - did it through CoW Protocol with small swaps to minimize slippage. Meanwhile, there's this interesting divergence happening between certain major exchanges where Bitcoin's trading at different prices, suggesting some institutional money might be pulling out.

On the regulatory side, Vietnam's moving forward with a 0.1% tax on crypto trades, treating it like stock transactions. Pretty straightforward stuff. Also caught that Pavel Durov, the Telegram founder whose net worth is estimated in the billions, is going hard against Spain's proposed online age verification laws - calling it a surveillance state move.

Some notable exits too: Bitcoin Core dev Gloria Zhao stepped down after six years as a maintainer, and Kyle Samani just left Multicoin Capital to explore AI and robotics. Both seem like significant shifts in the space.
