This is a good article, and aside from USD1, all the farming methods below seem good. Extended is also decent, with a 15-30% APR for King-tier, but considering all the factors, Binance USD1 seems the best.
When farming, I often consider the cost of nerves and the risk of hacking. Personal wallets can be vulnerable to a single device or a single transaction, making it difficult to keep large amounts of money in them for long periods of time. With sufficient security knowledge and thorough hardware and network management, I believe they can be more secure than centralized exchanges. However, I always think of myself as a Lazarus lunchbox, so I only take on risks that I can survive even if I'm hacked unexpectedly.
However, Binance, with strict multi-layer security settings like 2FA, generally has a lower risk of hacking than personal wallets. For USD1 events, there's no maximum cap, making it easy to participate. They also offer generous APRs to mitigate these risks, making them the best option at the moment.
I hope you can extend the remaining 3 weeks as scheduled.
