You have to be careful when it comes to staking. Any incentive should be looked at and considered when making an investment
But, in my entire experiences with cryptocurrencies, I have never come across a coin with staking feature and sustaining till date (ethereum could be the different one which may be due to its lateral introduction of this feature). I mean to say, all the coins which comes up staking feature losing its value over the time as people are immediately cashing out all the profits from staking. Clams, reddcoins are few of the coins I tried for staking, honestly I could not recall all my list of staking coins. But, no single coin survived still date from my list.
APR are not always accurately when the staking has started, you'll be promised 10% APR for example, but you'll be given something different from the agreed percentage when staking starts, it's always confusing and most dex haven't said the truth about their staking APR.
I am also staking TRX and ADA in some exchanges and wallet but I never followed the returns for meeting the promised APR. After reading your post, I guess that I must check my staking profits.
