Yes, BNB and the other exchange coins may give you similar returns. Probably not quite like what you asked, but you should also take a look at the masternode coins. They may give you much more than 5% of monthly return, but they have additional requirements. Masternodes require a minimal number of coins to be locked in a wallet. Usually 1000 coins, or more. The node has to be online all the time, which usually means you have to cover the expenses for hosting the node somewhere. But the return can be good.
Masternode coins are good source of income however, some good masternode coins are too expensive already that's why you should hunt for a coin that is not yet that expensive. There are several masternode coins you can choose from that are not expensive yet like CIF but then it's price is going down and has small volume but they are quite active so we have yet to see the effects of their efforts.
Besides doing stacking/POS, you can try referral program (no investing needed) in some crypto market exchange. I'm doing this in my local crypto market, I've never traded, but most of my referral is active (daily) traders so that I can get referral fee almost every day
. I don't know which market has the same program.
If you know how to convince others to join a certain website through your link then it would be a good way of having passive income. It applies to faucets as well wherein you can earn higher when you let others sign up through your link. You can use your marketing strategies in here as to how you would convince them to join and then you will reap the rewards later if they would be active.
