The cryptocurrency world has seen its fair share of ups and downs this week. Loopring, a zero-knowledge rollup protocol, announced a $5 million security breach in its two-factor authentication service. On the other hand, NFT sales volumes skyrocketed by 18.9%, with Bitcoin Ordinals leading the charge. Uniswap founder Hayden Adams also shared his thoughts on Ethereum Layer-2 blockchain networks.

Loopring's security breach allowed the attacker to reset wallet ownership and withdraw assets. The project shared two wallet addresses involved in the attack, with one holding over $5 million in cryptocurrency. Meanwhile, NFT sales volumes reached $147.3 million, with Bitcoin-based NFT sales surging by 57% to $49.7 million. Ethereum NFT sales saw a slight decrease, but other blockchains like Polygon, Immutable, and Blast saw significant growth.

Hayden Adams, founder of Uniswap, expressed his views on Ethereum Layer-2 networks, stating that they should prioritize scalability over immutability until the Ethereum mainnet is ready. His comments sparked a debate, with some calling Layer-2 networks a "money trap."

In conclusion, this week in crypto has been marked by both security concerns and market growth. As the space continues to evolve, it's essential to prioritize security and scalability to ensure a bright future for cryptocurrency and NFTs."
