a 10k Hive would bring, after a year, a projected profit of 5,480 Hive, a considerable amount, keeping in mind that the APR can change at any time.

It's a very attractive sum, this isn't a lie. I think the golden rule will be to use money that you're comfortable with losing. Why? I think anyone can make mistakes with their KYC and Binance will block their accounts. It's quite hard and stressful to unblock accounts locked by a CEX. I don't blame anyone for wanting 40% APR, but I believe people are adults and can make their own decisions
