FAQs
Is mining still profitable in 2024?
While less lucrative than 2021, efficient operations can still generate income, especially with optimized hardware and low electricity costs.
How risky is funding rate arbitrage?
The strategy carries exchange risk and requires constant monitoring. Historical returns don't guarantee future performance.
What's the safest way to invest in crypto?
Dollar-cost averaging into blue-chip assets (BTC, ETH) during bear markets has historically outperformed short-term trading.
