You have to be careful when it comes to staking. Any incentive should be looked at and considered when making an investment, but there are alt coins that use generous incentives as a way to lure unsuspecting investors in to take their money with pump and dump or other schemes. Just make sure you like the asset, not just the incentives.
That's one trick, offering a great APR so that they can attract more investors. But we don't know, they can change the rule anytime and then we all know that your funds are lock in and trap.
Maybe in the beginning staking has been great because it give one project more liquidity. But as time goes by, there could be many loopholes that investors might be set in and then there's no way out. So now, it's not as it used to be, so for me, it's not ideal unless you really knows what you are doing here.
