it give us more guarantee than staking in nashcash or any else. binance exchange provide high security protection to customer's fund , so its recommended if we put our money there. meanwhile we still doubt with nashcash reputation better to avoid it.
I've never heard of nashcash but it's something interesting because apy is so big, but very suspicious about reputation that it's not easy to trust anything new. It is recommended to staking on a binance exchange or pancake because it is much safer.
