Is there a way to know how many spendable merits are going to expire soon ? If not, it should be included in profile if possible.
The conclusion you can come to from your question is, the current Merit will not expire or decay until theymos add new rules to the system. So you can still use your sMerit at any time regardless of whether you got it from an airdrop or from another user. You can find out how much sMerit you can spend, but it will probably be the same if theymos start implementing sMerit expiration limits.
krishnaverma, can I know why it is good to add?
Well I don't know how this option will be helpful but I know theymos only add update only if they are very important so this particular feature wont be needed but that's for my own opinion although. We can all see how many merits we have so why bother for checking the expiration date although I understand how curiosity works.
