I am not recommending anything but here's the thing with these high APR staking projects. They're not stable and there is a tendency that those percentages will drop over the period of time. Once other stakers see the opportunity from within, they're not going to waste any moment and they'll also stake. So, the share that they're getting together with your stakes are the reason why these APRs are going to be drop once more demand on that stake increases.
The most reliable option is to stake stablecoins but if you are more risky person, you can try staking Altcoins.
I agree, this is running from 5%-15% and the highest could be 20%. It's quite safe but just as what I have explained, it can also drop in percentages over time when more people stake on that platform.
