The 1.72% over 14 days and 45% annually are the same scaled over different time periods, so it doesn't matter what the duration is. If you can't make a profit offering 45% on deposits for a year, you can't do it over 14 days either, so the question is why intentionally take on a money-losing endeavor? If Binance is a scam, you think they're gonna tell you because you asked them? I'm looking for other thoughtful people who might have information I don't about this. That's why I raised the question here. And it's further relevant in this thread because if FUN is owned by this website as was said in this thread, it's a legitimate question for the owners of the coin, especially if they're touting the return potential without regard for whether or not any of this has been vetted.
They have a cap on the amount of FUN that can be staked in this savings plan. Once they reach the cap people won't be allowed to subscribe to that plan anymore. If they are offering this for a limited time to it is certainly possible to offer these returns.
