Stablecoins Under Scrutiny

Amidst the market’s recovery from the recent onslaught of SEC crackdowns, rumors swirl over the potential targeting of stablecoins in their crosshairs. Such a move could have profound implications for cryptocurrency prices, making it crucial to gauge the likelihood of this scenario and the approach regulators might adopt. The largest stablecoins by market cap are Tether’s USDT and Circle’s USDC. Both are pegged to the US dollar and backed by various assets, typically highly liquid instruments like US Treasury bills. In theory, when someone wants to buy stablecoins from an

Crypto Chaos

Despite the second-largest bank failure in US history, the Federal Reserve continued its interest rate hike strategy last week. This caused markets to react by pricing in continued monetary tightening, pushing back their expectations of rate decreases to 2024. Some have perceived this move as necessary to combat inflation, even if it comes at the cost of breaking the banking sector. Unfortunately, this sober outlook suggests that the rest of the year may be marked by more sideways action in the markets rather than a steady recovery. Meanwhile, in the

However, with the help of TruthGPT, the future may offer some light on the capabilities of biased AI models, despite their ability to sow social discontent, promote cultural differences, and create

The Question of Liquidity

While many people consider valuation to be the most challenging aspect of NFT lending, the real issue is liquidity. When taking an NFT as collateral for a loan it would be a recipe for disaster to think it can be sold easily at all points in the market cycle. During 2021 NFTs experienced a huge uptake in their popularity. Some said this surge in demand was the cause of increased gas fees on the Ethereum network. However, in between the two peaks of this surge, there was a terrifying liquidity
